1.3.2 Project Workspace
The project workspace contains the overall layout of the structure.
The project workspace comprises of floor plan, column, wall, pad
footing and foundation footing. To select the element, left-click twice
on the element name to activate the element. You will be directed to
the selected element active window. There is a box next to the each
element name. The tick in the box indicates the particular floor
contains data or has been edited.
For example, if you have new floor and you want to create gridlines.
Before you input any data into the floor, the box is empty. Creating a
gridline will activate the tick in the box. This shows that the floor has
been edited.
To run column, wall, pad footing and pile footing analysis/design,
double click on the box next to the element names. Analysis for some
elements will only run after certain analysis has been performed. To
learn more about the sequence of the analysis, please refer to Esteem
Flow Design Flow Chart. For example, to run wall design, you have
to run the 3D-analysis first. After successfully performing each
analysis and design, box will be ticked. You can then proceed to the
next element analysis.
You can close the project workspace window by clicking the cross at
the top right corner at project workspace or right click on the menu
bar deselect the project workspace. To enable project workspace, go
to menu bar, right click once and a menu will be shown. Click on
project workspace to bring up the window.
1.3.3 Tool bar

command performs the same function.
Each button carries a brief description of its function. To display
these functions, move the cursor to the button, hold for a few seconds
without clicking it and the description will appears. You can also
view the descriptions at the bottom left corner of the window.
The tool bars in the program are not customizable. However, you can
display or hide the tool bar buttons to your preference. Hiding certain
tool bars will not allow you to carry out certain functions which are
not in the menu bar. To display the tool bar, right click on menu bar
and select the tool bar you wish to display.
1.3.4 Menu bar
Menu bar contains topics that are divided into groups and categorized
according to the related functions. The menu topics contain related
commands that are relevant and closely associated to the menu topics.
For example, Save command allows you to save the project and this
is a general command. Hence it is categorized in the File menu. To
access a menu, left click on the menu and this will slide down a list
of submenu commands. Left click once to select the commands. Each
individual commands are described in latter chapters of this manual.
1.3.5 Main title bar
The main title bar describes the program name and the current
installed version. It also displays the active window name and the
description of the tasks. For example, you want to input slabs into the
second floor. You activated second floor named 2b by double left
click the element in project workspace. In main title bar, it will
display "Esteem Structural Software 6.x.x.x - [Plan View 2b]

1.6 Working with other programs
EsteemPlus is a stand alone program and do not require any
compliment software to fully utilize the program. However
EsteemPlus output files can be assessed using other programs. The
file types and the associated programs that use these files are
described as follows:
1.6.1 CAD Programs
Save as DXF file format: You can transfer detail drawings into
CAD related programs. DXF format is an AUTOCAD data
interchangeable file. It is a CAD vector format designed to allow the
exchange of vector information between CAD applications. This
DXF file saved can be open with any Computer Aided Drawing
software such as AUTOCAD and INTELLICAD.
Plan views can be saved as DXF file. You have the options of save as
construction drawing or save as what you see on the screen. Save as
construction drawing selects only layers that are considered as
common practice in the detailing of construction drawing.
Save as what you see on the screen selects layers that are displayed
on plan view. Layers that are hidden or turned off will not be saved
in the DXF file.
1.6.2 Zip Programs

Define number of floors
• Number of key plans allows you to define the number of floors.
• Insert Floor enables you to add each individual floor.
• Delete Floor allows you to delete the selected individual floor.
• Fill Default automatically names the floor plans by default.
In data table under Floor Name, you can rename each floor to your
preferences. When you have defined the floor properties, click OK to
accept your selections. Clicking Cancel button cancels the changes
you have made. After selecting OK, working folder for each floor
will be created under the main project directory.
Note : You are not allowed have floor name ending with a
number. The reason of this is due to the naming style of the beam
which follows the floor name. For example, if you name a floor to
GF1, then the beams mark would begin from GF11, GF12, and
Esteemplus

3.2.1 Reset Project Analysis Result
Selecting this command resets all the current project analysis results.
Any analysis results performed will be permanently deleted. You will
not be able to retrieve the results once you selected this command.
Note : This command is useful when you have trouble
assessing the project. When the program performs analysis and
stalled during analysis, the analysis will be incomplete and the
results data would become corrupted or invalid. Clearing the
corrupted results would allow you to assess the project.
3.2.2 Check Project Grid Integrity
This command allows you to check the grid integrity of the whole
structure. The program performs integrity checking for any grid
discrepancy between each floors of the structure. The program
reports gridlines with any discrepancy.
Grid discrepancy occurs when two or more grid marks between
floors that do not match. For example grid mark B of floor GB is
4000mm from grid mark A while grid mark B of floor 1B is 4100mm
from grid mark A. The inconsistency in dimensioning of the same
grid mark B in different floors creates grid discrepancy.
You are not allowed to name differently for the same gridline
position in different floors. The program detects this discrepancy in
grid integrity check. For example, for the same position of gridlines,
you named gridline on floor GB as grid mark A. However on floor
1B, you have named the same gridline as grid mark A1. This is not
allowed and the program reports discrepancy in this particular case.
Menu
3-29
3.2.3 Check Project Integrity
Using this command initiates the program to check for the global
structural integrity. Any warning detected prevents further analysis
until problem is resolved. The program highlights the element which
contains error. The program performs checking on the following area:
Check transfer column: The program checks for valid transfer
column in the model. Transfer column can be supported only by
beam or wall.
Check for column: The program does not allow column offset from
the position out of the column area above or below it. The program
does not consider eccentricity into column design. However in
column design, moment due to minimum eccentricity will be checked
by the program.
Check for wall: Detects any created wall for every floor.
Check for wall opening: Detects any wall opening for every created
wall.
Check rc wall overlap: Detects any overlapping walls.
Check rc wall opening overlap: Detects any overlap opening in the
same location. If wall openings overlapping are detected, the program
automatically deletes the later created opening.
Check wall data for individual floor: Performs checking on the
validity and consistency of data for wall.
3.2.4 Adjust for Datum Distance
This is applicable only if you import project from EsteemWin
Version 5.2. With the variation in gridline input between EsteemWin
Esteemplus
3-30
and EsteemPlus, gridline's dimension from the imported project data
requires adjustment. Click on this command to refresh the imported
gridlines in EsteemPlus. This is due to the different style in creation
of gridlines for Esteem software.
3.2.5 Progress Bar
During analysis, project status bar appears on the window showing
the progress of the analysis. In certain cases after the analysis, the
status bar remained on the window. Click on the progress bar
command to remove the status bar in the window.

6.1.5 3D Analysis Parameters
3-D Analysis Options:
· Wind load analysis: Checking Wind Load Analysis box
performs 3D analysis although there is no wind load applied
to the structure. Notional load will also be automatically be
considered during the 3D analysis.
If the program detects RC wall created in the model, it
automatically enables 3D analysis.
· Pin foundation: Checking this option set the all columns
bottom condition at foundation level to be pin restraints
during 3-D analysis. This is not applicable for shear wall that
acts as vertically cantilevered beam from the ground.
Disabling this option will not support the design for
foundation designs in later stages. Currently, the program
does not support moment design for foundation.
· Slab diaphragm effect: Selecting this option considers the
slab diaphragm effect in the 3D frame analysis. The lateral
loads acting on the structure will be transfer horizontally
throughout the floor slabs to the main lateral resisting
element.
· Double precision in analysis: Checking this option allows
the program to perform more iteration in equation solving to
provide more precise results. However more resources are
used to perform this analysis and this might affects the
performance of your computer.
· Notional analysis: Enabling this option considers notional
load case in the 3-D analysis. User can specify the percentage
of notional load for the analysis.
Esteemplus
6-70
Ground Floor Non-Suspended Slab:
Enabling this option assumes that non-suspended slabs at ground
floor provide restraints to the column. The program considers this
effect and determines the effective height of the column. Disabling
this option allows the program to determine the effective column
height based on restraint conditions. This is only applicable when
there are only slabs (without beams) connected to the column at
ground floor.
Note : This option does not affect the slab design at ground floor.
For non-suspended slab on ground floor, simply do not create any
slab on this floor.
Concrete Properties: You can enter any value of Young modulus E,
and Poisson Ratio V in this text box .The default value of both
properties is base on BS8110
3D Frame Generation Options:
· Maximum and Minimum RC wall mesh size: This option
allows you to specify the maximum and minimum mesh size
for the liftcore and shear wall. The smaller the mesh sizes
defined, the more precise the results are. However this will
also take up more of the computer resources and might affect
the overall performance.
· Slab diaphragm mesh size: Selecting this option considers
the slab effect into the frame analysis. The lateral loads
acting on the structure will be transfer horizontally
throughout the floor slab to the main lateral resisting element.
· Gradient effect: If this is activated, the triangle mesh
generated is more uniform (please refer to figure 1& 2 at
Section 12.9) and the FEM analysis is more precise.

6.1.6 Automatic Element Optimization
This feature allows the program to determine and modify the element
(dimension), when the specific element fails in design. All the failed
elements will be optimized according to user defined parameter.
Please refer the following example for this application.
Example: The FS1 slab of the following example is design to Auto
optimization. Slab FS1 thickness is set to 125 mm. Let say you have
a floor plan consisted with slabs. The remaining of the slabs is
created with thickness of 200mm. After slab analysis and design
(refer to chapter 12.3), the program found that the FS1 slab has fail.
With the auto optimization option turned on, the program
automatically increases the thickness of slab by the user defined
increment. In the user defined incremental table, each increment is
25mm. The program will back calculate the required slab thickness
and increased the thickness to the nearest increment. Say the required
thickness is 135mm However since the incremental value is 25mm;
the program automatically increases the slab thickness to 150mm
(25mm increment).
Once the program automatically increases the slab thickness, you
have to rerun the slab design.
Note : If the Auto optimization option is turned off, the program
will let you know which element failed in design, instead of
modifying the element properties.

requires 200mm thick. With the minimum footing thickness
set at 300mm, the pad footing adopts 300mm thick instead.
· Incremental dimension figures for footing dimension
(mm): This option allows you to specify the dimension
increments for the next footing size. Footings are
automatically grouped to similar sizes based on the load
capacity. Smaller dimension increments increase the number

x 1200, 1250 x 1250, 1050 x 1050 and 1400 x 1400
respectively. If you set the incremental dimension to 100mm,
the program will sort into 3 types of footing sizes. The 3
types of footing sizes are 1050 x 1050, 1250 x 1250 and 1400
x 1400. Any footing sizes within 100mm increment are
grouped into the same type of footing.

For example, you have a column reaction dead load (G) and
live load (Q) of 100kN and 50kN respectively. You have set
15% load allowance. For load combination of 1.4G + 1.6Q,
Ultimate load = 1.4 x 100 + 1.6 x 50
= 220 kN
Load allowance = 15%
Final ultimate load with load allowance = 220 x 1.15

Beam Subframe Design Configuration
The program allows you to select the method of analysis you want to
adopt for your design. In the Beam Subframe Design Configuration
area, you have the option of:
· Subframe design for beam: Checking this option allows the
program to analysis the model using subframe analysis
method.
· Pin support condition at first and last supports: This
option allows you to set the beam support conditions to pin
fixity at first and last support. For monolithic structure in
frame design, the first and last supports carry moment.
However overwriting this condition to pin support allows the
moment to redistribute the moments to the internal span.
Continuous Beam Design Control Factors
You can analyze the structure using continuous beam method.
However the continuous beam method requires satisfying the factors
below. If any of the factors being exceeded, the program will run
analysis adopting subframe design analysis.
· Beam span greater than (mm): This option allows you to
specify the maximum allowable beam span for the
continuous beam method. The program automatically
converts to subframe analysis if beam span is greater than
value specified here.

· Maximum difference span's width for continuous beam
analysis (mm): This option allows you to specify the
maximum difference in span's width to consider as
continuous beam. For example, you have set this value to
100mm. You have two adjacent span beams with width of
125mm and 250mm respectively. The difference of beam's
width is 125mm and it has exceeded the allowable difference
width of 100mm. Therefore the program considers these
beams as simply supported.

7.2 Click grid and drag method
This function enables you to create grid lines using the graphical
interface. To create a grid, point the mouse cursor on the previous
grid line. Note that the cursor will change to a cross once the cursor
is pointed to the grid line as shown in figure 7.1(a). Click on the grid
line to select, drag the grid line to the next grid location and left click
once to create shown in figure 7.1(b) below. Each dimension
increment is by +/- 100mm. To adjust dimension by +/- 10mm, press
UP arrow to increase and DOWN arrow to decrease the dimension.
For increment of +/- 1mm, hold CTRL key and press UP/DOWN
arrow keys. To cancel the grid selection, right click once or press the
ESC key.
a) Cursor changed to cross when at gridline
b) Extending the grid line dimension
Figure 7.1: Example of creating gridline
Esteemplus

You can create the grid line from any reference grids in the same
direction. You can rename the grid to your preference by clicking
twice on the grid label and type in the grid mark. You can also
modify the dimension of the grid by clicking twice on the dimension
label at the bottom grid and type in the new dimension.
Note : If you want to edit the dimension of the major gridline with
minor gridlines in between, you have decrease the indent of the
minor gridlines before editing the dimension. The new dimension
specified actually begins on the previous gridline. The program
cannot differentiate between major and minor gridlines.
For example, you have gridlines labelled A, A1 and B. Grids A1 and
B are located 1000mm and 4500mm respectively from grid A. Grid
A1 is a minor gridline. Refer to figure 7.2 to 7.5 for further
information. You want to change the dimension of Grid B 5500mm
from Grid A. Double click on the dimension at the bottom grid and
specify 4500mm. This is because the dimension of Grid B begins
from grid A1 and not from grid A. If you modify Grid B dimension
to 5500mm, the final dimension of Grid B from Grid A is actually
6500mm from Grid A.

Figure 7.5: To achieve Grid B 5500mm from Grid A, the dimension should be input as
4500mm instead of 5500mm
If you create a new gridline to the left direction from the initial
gridline, the program will name the new gridline based on the last
defined gridline. You have to change the grid mark manually in table
properties if you prefer another grid mark label. For example, starting
y-direction grid line mark is labelled as A and the last gridline you
Esteemplus
7-116
have defined is labelled as E. If you create a new gridline to the left
from grid mark A, the grid mark will be label as F.
Tips: Create major grids first and add the minor grids later.
This creates a regular naming to the labels of the grid lines.
Note : The distance between 2 grids must be more than 300mm.

7-117
7.3 Using grid generator
Clicking Batch X Grid Input button brings up the multiple grid input
form as shown in figure below where you can specify the number of
grids of your choice. All dimensions are in millimetres, mm.
Figure 7.6: Multiple Grid Input
To enter multiple grids with different dimensions, specify the grid
dimensions followed by the comma. This will generate the grids
based on your specified input.
If the grids are symmetrical, input the dimension followed by 'x' and
the number of grids you which to input. The program will duplicate
the dimension to the proceeding number of grids defined.
You can also use the combination of the above methods to create the
grids.
For example suppose you have 3 grid lines with dimensions of
3500mm, 4500mm and 6000mm respectively in the x-direction. Thus
input 3500, 4500, 6000 in the x-direction grid form. You have 10
grid lines with dimensions of 4500mm respectively in the y-direction.
Esteemplus
7-118
Input the 4500x10 in the y-direction grid form. This will generate 10
grid lines with dimensions of 4500mm for each grid.
Note : You cannot input negative value for the grid dimensions.
This is not a valid input to the program.

7.4 Table input
You can edit the existing grid properties by using the general
properties as shown in figure below when the input grid is activated.
Figure 7.7: Grid Properties Table
The General Properties allows you to modify the following:
· Rename grid mark allows you to replace the existing grid
mark. You cannot have multiple gridlines with the same grid
mark.
Note : You cannot input symbol at grid mark. Symbol defined
in plan layout is not recognized in the DXF file. Therefore you
cannot access the saved DXF file in CAD software.
· Modified the distance of the specified grid. You can input the
gridline distance with a minimum of 300mm (0.3m) to
maximum of 100000mm (100m). Negative values are not
allowed in this component.
· Rotate the grid in degree. Positive degree denotes clockwise
rotation and negative degree denotes anticlockwise rotation.
The rotation point is situated at the bottom of y-direction.
Note that the slanted grid cannot intersect with other gridline.

8.2 Beam generator wizard
You can generate beams in each direction using the beam generator
wizard . Selecting this command generates beams to all the
grids in the respective direction automatically. Generated beams have
the same properties such as size and drop. You can edit each
individual beams using the table properties.
For example, to generate beams on the x-direction gridlines, input the
general beam dimension say 230x450 in table properties located on
the right side of the window. After you have input the beam
properties, click x-dir beam generator command. Beams of
230x450 within the x-direction gridlines will be created.
Note : All previous beams created will be overwritten and replaced
with the generated beams.
Tips: This feature is useful if you have many similar beam sizes in
the plan layout. It is faster and easier to generate beams and
then make changes on the individual beams later.
Esteemplus

8.3 Beam Table Properties
In the table properties, you can modify the concrete section, offset
and set the drop of the beam. Click on the Input Beam icon, to
activate the table properties. Before creating a beam, specify the
beam properties. Left click once to accept changes. Now create beam
using the methods discussed under topic "Click and Drag Method"
and "Beam Generator Wizard".
You can also modify the beam properties after you have created the
beam. Click on the beam and the current beam properties will be
displayed in the table properties. Specify the new properties of the
selected beam and left click once to amend changes.
You can modify beam properties to the following items:
· Width of the beam in mm
· Depth of the beam in mm
· Drop in beam (mm): Positive value denotes drop while
negative value denotes raise level.
· Offset of beam (mm): Positive value denotes rightward or
upward offset in plan while negative value denotes the other
way.
· Bottom Bar Direction: Manually redefined main
reinforcement bar direction.
· Span/Depth Options: You can manually define this value or
let the program determines for you.
8.3.1 Auto Optimization
You can manually select the specific dimension to auto optimize in
here. To do so, simply select the beam you want and tick the Width
/Depth option. To deactivate the specific element auto optimization,
just select the specific element and untick the Width /Depth option.

8.4 Input Beam Load
8.4.1 Point load
You can create point load at any point on the beam. The Point Load
command creates a point load on the beam. Clicking the point
load command brings up the load magnitude table on the right side of
the window. In the table, you can input dead load and live load or the
combination of both. The unit for the point load is kilo Newton (kN).
Move the mouse onto the beam you which to add point load and the
cursor changes into an icon. Click on the mouse left button once to
select the beam and the cursor will lock the selected beam. Move the
cursor to the right to specify the position of the point load. Click once
on the mouse left button to create the point load. Once selected, by
default a red dot for the point load will appears on the beam. The
point load position always offsets from the left or bottom of the
gridline.
For example, you have a beam on grid A, B and C spanning 3000mm,
4000mm respectively. You create a point load on the beam, 5000mm
from grid A. Move the cursor towards 5000mm, upon passing
3000mm, the distance begins at the second span from gridline B.
Clicking the mouse left button at 2000mm will give you 5000mm
from gridline A.

Uniform distributed load is a load of constant magnitude applied
along a length of a beam or and area of a surface.
Click Input Beam UDL command brings up the load magnitude
table on the right side of the window. Input dead load and live load in
the specified form. The unit for UDL is kilo Newton per metre
(kN/m). Move the cursor to the beam and the cursor changes to UDL
icon. Click on the beam once to lock on the selected beam. An active
box displays the position of the starting point of the UDL either from
the bottom or left of the grid. Move the cursor to select the UDL
starting position. To define the starting point of the UDL, move the
cursor to the specific distance and click once. The active box then
displays the distance for the UDL end point. To select the end point,
click on the left button once.
Note : Uniform Distributed Load, UDL always offsets from the
left or bottom of the grid.
For example, you have a two spans beam separated by grid A, B and
C with 3000mm and 4000mm respectively. You want to create a 5
kN/m uniform distributed dead load starting from 2000mm and
ending at 4000mm from grid A. Select Input Beam UDL command
and define 5kN/m dead load in the table properties. On the selected
beam, move the cursor 2000mm from grid A and click once to define
the starting point. Move the cursor 1000mm from grid B to select the
ending point. Click on the left button once to select. Once created,
you can see the UDL magnitudes and positions of the UDL on the
key plan layout. By default, the UDL is indicated as red colour hatch
on the key plan layout as shown in figure 3. You can change the
hatch colour to your preferences, by selecting layer settings
command.

8.4.3 General Variable Load
You can create non-uniformly distributed load such as trapezoidal
and triangular load using General Variable Load, GVL
command. To create general variable load, click GVL command
to activate the load magnitudes table. There are 4 entries in the load
magnitude section as shown in figure 8.10. The first dead and live
load start from the left or bottom of the grids while the second dead
and live load end the loads. You can modify any created loading
positions using the load position table.
Figure 8.10: Load Magnitude Table Input
Warning : You cannot leave load magnitude entries blank. This
generates an infinite value and will create error to the program. Set
the entry to zero instead of leaving it blank.
To create different type of loading patterns, you have to specify the
load magnitudes accordingly as shown in figure x. In the figure
below, X and Y represent the load magnitudes respectively and 0
represents zero/nil. Type 1 and 2 are for triangular loads while type 3
and 4 are for trapezoidal loads input.

Figure 8.11: Type of variable loadings
For example, you have 2 continuous span beams of 3000mm and
4000mm respectively marked by grid A, B and C. You want to create
a 2000mm triangular load, 4000mm from grid A. From left side, the
triangular dead load increases from 0 to 5 kN/m. Click on the GVL
command and input 0 and 5 in the first dead load and second dead
load entries respectively. Since there is no live load, input 0 to both
first and second live load entries.
Select the beam by clicking once and move the cursor 2000mm from
grid A. Click once to define the starting point of the triangular load.
Move the cursor 4000mm from grid A. Note that when the cursor
moves further than the beam spanning between grid A and grid B, the
dimension display resets and begins at grid B. Now move the cursor
1000mm from grid B and click once to set the load end point.
After creating the load, the load properties are displayed on the key
plan layout. DL and LL denote dead load and live load respectively
while SO and EO denotes starting offset and ending offset
respectively.

8.6 Beam Offsets
You can offset the beam to flush with the column. To offset a beam,
select the particular beam and specify the figure in the Position table
on the right of the window. Left click or press Enter to confirm the
changes made. The beam offset is based on the centre of the gridline.
Input negative figure shifts the beam to the left/bottom of the gridline
and positive figure shifts the beam to the right/top of the gridline.
You can offset the beam using the offset wizard. These features can
automatically offset the beam to the left, right, top, bottom and centre
of the grid. Figure below shows the description of each offset
commands.
Table 8.1: Beam offset commands
Beam to beam offset
When you offset the beam located perpendicular to a beam, the actual
position of the beam is updated to the perpendicular beam. For
example, you have two beam, primary beam GB1 and secondary
beam GB2. Primary beam GB1 spans 5000mm from Grid A to Grid
C. Secondary beam GB2 is positioned along Grid B. Grid B is
located 2500mm from Grid A. Secondary beam GB2 without offset,
is 2500mm from Grid A as shown in figure 8.16. If you offset beam
Creating Beams

9.6 Column Bracing Condition
To determine the column end conditions, the program calculates the
beam/column stiffness, k ratio. The program assigns the column end
conditions based on the ratio below:
Beam/Column
Stiffness, k
Column fixity End condition
1 <= k Fixed 1
1> k > 0.1 Partially Fixed 2
k < 0.01 Pinned 3
k = 0 Free Cantilever 4
Special Cases
Condition 1
If X Direction column End Condition == 4 AND Y Direction column
End Condition < 3
Then X Direction column End Condition = 3;
Condition 2
If Y Direction column End Condition == 4 AND X Direction column
End Condition < 3
Then Y Direction column End Condition = 3
User can view the column end conditions assigned by the program in
the Column Detail View > Column Design Report .
Alternatively, you can access the report file with *.crr extension
outside the program using Word related program. For example, if
your project is named as BuildingA; then the column design report
file would be BuildingA.crr located in the project folder.
Note : You must perform column design to access this report.

12.1 Generate slab mesh
Clicking the Generate Slab Mesh command activates a dialog
that controls the mesh generation settings. In this dialog you can
specify the maximum mesh size and the mesh type. By default, the
mesh size is set to 500mm. The accuracy of your results increases
with smaller mesh sizes as more unknown displacements are
involved. However smaller mesh sizes take longer to analyze due to
more equations involved. This requires more resources from your
computer.
In the dialog, you can also select the type of mesh you want to adopt
in your analysis. You can select triangular, mixed or quadrilateral
mesh in your slab mesh generation. Click OK to generate slab mesh.
Slab Internal Column Model Options
You can set the number of nodes available at the column during mesh
generation. Check on either model as single node at the column
centre or model as 8 nodes along the column edges. Selecting model
as 8 nodes along the column edges option provides nodes at the
column edges and middle column faces. The program automatically
applies the additional nodes to the column supporting slabs only.

parameter form you can select the following options:
Default Column Optimization Options:
Optimize Dimension (mm) with selection of incremental size and
permissible optimization limit on following directions:
· X direction· Y direction
Circular column settings:
You must activate X-direction check box for the circular column
auto-optimization to run since the input for circular column diameter
is on the X-direction. If you have activated the Y-direction auto
optimization, the program performs no action on Y-direction
dimension incremental.
Default Beam Optimization Options:
Optimize Dimension (mm) with selection of incremental size and
permissible optimization limit on following dimensions:
· Width· Depth

· Thickness of wall
Default Slab Optimization Options:
Optimize Dimension (mm) with selection of incremental size and
permissible optimization limit on following dimension:
· Thickness of slab
User Defined List
For each element optimization options, user can defined specific
sizes for optimization up to four lists. In these lists, set the
incremental sizes to be adopted in the auto-optimization.
If the incremental sizes exceeded the user defined list, the program
displays the warning after the element analysis/design.
Concept:
Beam optimization
In the Project Parameters > Automatic Element
Optimization, specify the dimension sizes permissible in the
respective lists. In list 1, define the allowable width while in list 2
define the allowable depth for the optimization.

Fig 3: Defining dimension allowable in respective list
Activate the Input beam command to create beam. Click on the
beam; on the properties table, user has the options to optimize the
width, depth or both dimensions when necessary. Check on the boxes
on respective dimensions for optimization. Once user checked on the
tick box, noticed the selected dimension increment will be available
for selection.
For example, user has activated depth optimization; in the pull down
list select List 2. The list 2 is the same list defined in the Automatic
Element Optimization parameter.
Beam optimization parameter setting
Note : The governing factor for the optimization is the
maximum steel percentage allowed % which by default is set at
2.0% of the area of beam section.

Say, based on the list 2 in figure 3;
1) Initial sizing (width x depth) = 100mm x 100mm è failed intension exceeded 4%.
2) Next size up based on list 2 = 100mm x 300mm è failed intension exceeded 2%. (Due to setting for maximum steelpercentage allowed).
3) Next size up based on list 2 = 100mm x 450mm è ok intension < 2%. (As defined).
4) Therefore the final size is 100mm x 450mm. (With widthoptimization not activated)
Note : This example is only applicable for project basis. User
can also define the list in the parameter template to be adopted in
the newly created project.
