MAIN

FEATURES

WS BEAM SCHEDULE takes data from ETABS, after calculating and evaluating based on your

preferences, it generates reinforcement values. In addition to that it suggest reinforcement

bars for final CAD beam schedule, doing all that in seconds without any space for errors.

1) Ea s y a n d c l e a n i n p u t by selecting a single report file from ETABS.

2) Automatically selects nearest bar dia for main bars, stirrups and side bars.

Checks for maximum side bars spacing.

3) User can increase reinforcement or specify minimum reinforcement values.

4) A u t o m a t i ca l ly d i s t r i b u t e s t o r s i o n r e i n f o r c em e n t for stirrups, side bars, top

and bottom steel .

5) Takes maximum of top reinforcement at end sections of continuing beam spans.

6) User can specify to make top and bottom reinforcement same, top left and top

right same, can select minimum bar dia of main and secondary bars etc.

7) D i f f e r e n t t y p e s o f o u t p u t s , can print Area required vs Area provided

comparison with values and percentages, can print suggested bars with

reinforcement values or only the suggested bars for CAD.

8) Takes beam properties from ETABS properties not from beam names so

eliminating the error of dimension difference between ETABS and beam schedule.

9) El im i n a t i n g a n y p o s s i b i l i t y o f e r r o r in reinforcement values as it takes the

exact values from ETABS, calculates, evaluate and present a final reinforcement

value including torsion reinforcement.

10) Takes less than 10 seconds to build the schedule and s a v e s m o r e t h a n 7 0 %

o f t im e taken to make manual beam schedule from ETABS.

Limitations

1‐No. of layers, and no. of bars: In current version, program determines required bar dia only for 1 layer.

No of bars in that single layer is determined by dividing the beam width by 100 and

rounding it to nearest whole number. For example 250mm will generate 3 bars. If

reinforcement value

from

ETABS

is

more

than

the

highest

bar

area

defined

in

Details

sheet by the user multiplied by the number of bars in single layer, program will calculate

the number of bars for the largest bar and report that value in beam schedule

irrespective if those number of bars can be accommodated in beam width or not. It is

Engineer's responsibility to check for these highly reinforced beams and select suitable

layers or reinforcement.

2‐Local axis: Beam local axis 1‐1 must be compatible with each other. For example all x beams must have

their local axis towards right. Similarly all y beams must have their local axis up. For

instance If some x beams have their 1‐1 axis towards right and others towards left for a

single

beam

of

many

spans,

the

reinforcement

values

for

TOPLHS

&

RHS

may

be

mirrored i.e. LHS may become RHS and vice versa. To avoid this it is recommended and

also a good modeling habit to always make local axis of elements compatible with each

other. Otherwise you can make use of the option; LHS=RHS in Details sheet to take the

maximum of RHS and LHS.

3‐Hidden data & sheets: This program stores and hides some data in hidden sheets, cells and rows to

calculate results. Please do not unprotect the sheet or delete any part. If you

want to change the code or formats, please contact the developer.

4‐Improvements: Improvements for sheet are under development. Settings and Details sheet will

be merged

in

next

version.

Everything

in

green

color

will

be

available

in

next

version.

5‐Same beam designation at various locations: If you want to use same beam designation at various

locations you can specify different beam names to it and later on select the

beam having largest reinforcement. For example if you have BEAM 3 at 4

different locations in drawing, you can in this program define it as BEAM3A,

BEAM3B and so on.

6‐Report from ETABS: Please select only beams not columns in ETABS. Do not select beams from

different stories. No beam should be overstressed. Always select INPUT and

OUTPUT when making report from ETABS. Do not edit that file. If program finds

any of the above violations, it displays an error message to the user and aborts

the process.

7‐Others: Please read help menu. Currently this version works for SI units (mm).

HOW TO

STEP_1: Please select the beams (only beams from same story, see Limitations note 6) in

ETABS, go to File menu > Print Tables > Concrete frame design (this option will

be available after making concrete design). Select INPUT & OUTPUT options only

and save

the

file.

Please

select

mm

units

in

ETABS

before

creating

report.

STEP_2: Open WS BEAM SCHEDULE, enable the macro warning in EXCEL, select BUILD

BEAM SCHEDULE in Beam schedule sheet, select ETABS generated report file.

STEP_3: Go to BEAM NAMES sheet, copy names from BEAM SCHEDULE sheet to here and

change them according to your drawing. Press UPDATE NAMES.

STEP_4: Change the settings in Details and Settings sheets until you arrive at your final

schedule.

Help Menu

1‐Beam labels: Beams in ETABS are identified by a beam label. You can show this by going to view

options and turning on the "Beam labels" option. Right clicking on the beam in ETABS

main screen also shows beam labels in properties window. Obviously these arbitrary

beam labels cannot be the part of final design drawing beam schedule. For this reason,

you have to change the beam names to your drawing beam names. After clicking on

"Build Beam Schedule", copy your beam labels in column "G", goto "Beam Names"

sheet, clear the entries and paste. Enter a beam name against each beam label. Beam

spans will be calculated automatically. There are various methods that can aid you in

writing beam names such as;

i) Print ETABS floor plan with beam labels and CAD floor plan on A3. Keep

them in front of you and start changing the beam names.

ii) Export ETABS floor plans to DXF format with beam caption option.

Please select suitable text height. Now overlay this DXF on your CAD

drawing, provided you have same units, origin and scale etc. Select all in

the drawing, click filter and filter only TEXT layer which was exported

from ETABS, move it little sideward so that when you print, ETABS labels

and CAD

beam

names

do

not

overlap

each

other.

Print

this

final

drawing

on A3 and start changing the beam names.

2‐Main reinforcement: Main reinforcement values are obtained from ETABS report. Final values

are reported after the following procedure:‐

i) Although ETABS checks the minimum reinforcement, user can still

provide minimum reinforcement ratio in Settings page. User can also




www.ranawaseem.com

provide increase factors in Details sheet. A factor of 10 means, increase

the reinforcement by 10% or multiply by 1.10.

ii) If after increasing the reinforcement value from ETABS by the user

increase factor still remains less than minimum reinforcement provided

by user,

it

takes

the

minimum

reinforcement.

Minimum

reinforcement

check is ignored if the ETABS value after increase factors becomes more

than minimum reinforcement provided by user. This is done to avoid

too conservative values. It is recommended to make minimum

reinforcement check equal to zero and increase the reinforcement by

some factors. You may even use ETABS values as is without any increase

but in some cases it may be desirable to increase the reinforcement to

cater for future changes or overload at site, redistribution of moments

etc.

iii) Torsion reinforcement (if any) is divided in perimeter of the beam

according to each side share. All sides of beam will have different share

of torsion reinforcement according to their length divided by total

perimeter of beam. Part of total torsion reinforcement that will go to

either top or bottom of the beam will be added to main steel at top or

bottom. Note (i & ii) will be applicable to this total value. It is Engineer's

responsibility to make sure that this reinforcement is at the perimeter

of beam and enclosed by ties as per code requirements. Other torsion

distribution options will be available in next version.

iv) You can make TOP LHS = RHS in Details sheet. It will take maximum

of LHS

and

RHS.

You

can

also

make

use

of

the

option

TOP

= BOTTOM

to

make top and bottom steel same. If you select this option then TOP

LHS=RHS is automatically checked and maximum of all three i.e. TOP

LHS, RHS and BOTTOM is selected.

v) You can specify minimum bar area for main bars in Details sheet.

Program will automatically select the bar designation based on this

area. For example you may want to restrict minimum dia of bar equal to

T16. This option will not affect the TOP MIDDLE.

vi)

Program

automatically

takes

the

maximum

of

RHS

of

previous

span

and LHS of next span of the same beam assuming beam spans are from

left to right. (See note 2 in Limitations.)

vii) Current version does not check min or max bar spacing within a

layer and other code specific requirements.

3‐Top Middle or Secondary Reinforcement: Top middle reinforcement for a beam is taken from ETABS

results. In some situations beam can have considerable amount of

reinforcement at top middle of a beam after analysis from ETABS. So this

program takes that original value and then checks user provided options such

as:‐

i) Minimum reinforcement ratio in Settings sheet does not applies to

Top Middle reinforcement.

ii) TOP middle reinforcement is increased by factor in Details sheet.

iii) Smallest bar is chosen based on bars defined in Details sheet. Min

bar area for main bars option in Details sheet does not affect TOP

MIDDLE.

iv) If top middle reinforcement is less than some %age of bottom steel

as defined

in

Details

sheet,

it

is

increased

to

satisfy

that

%age.

This

%age

is multiplied to the final bottom steel value (after min reinforcement

and increase factors checks.) This may be required by codes in seismic

detailing section. If settings in ETABS are configured properly, ETABS will

automatically take care of the minimum reinforcement values at this

section according to seismic provisions. Otherwise you can always

specify some percentage to make sure TOP MIDDLE section has at least

this percent of capacity of BOTTOM section. There is no similar check to

compare with TOP LHS or RHS at this time in current version.

v)

In

current

version

there

is

no

check

on

the

diameter

difference

of

bars between top middle and bottom or top LHS or RHS. In some cases

if for example top LHS = T25 bar you may want to specify top middle

bars not more than 2 bar dia difference.

vi) Enforce top LHS=RHS and Enforce TOP = BOTTOM does not affect

TOP MIDDLE bars.

vii) If beam length is very small, TOP MIDDLE bars are kept same as that

of top LHS and RHS or in other words, top reinforcement is continued

throughout the span. This limit should be checked by the Engineer.

vii) No. of top middle bars is calculated based on following formula:‐

if min of (LHS or RHS) => 4, then no. of top middle bars = 2 +[ 4‐min of

(LHS or RHS) ]

if min of (LHS or RHS) < 4, then no. of top middle bars = 2

4‐Stirrups: i) Av/s and At/s values are taken from ETABS report, increased by the

factors specified by user (See note iii). No minimum check is performed.

It is assumed that either user will check the minimum requirement or he

as configured settings in ETABS properly to take care of this check.

ii) No.

of

stirrups

are

increased

to

2 after

a certain

width

in

Settings

sheet. If beam is very wide Engineer may increase number of stirrups.

Currently in this version, program checks only for maximum 2 stirrups.

iii) Reinforcement increase factor in Details sheet is applied to the

combined (Main shear Av/s + Torsion shear At/s).

iv) It is Engineer's responsibility to make sure that stirrups should be at

the perimeter of beam and should be closed for torsion. An additional

note may also be provided in beam schedule. In current version,

program reports the number of stirrups required combined for shear

and torsion

but

does

not

add

a note

in

beam

schedule

for

this

torsion

condition. This should be done by the Engineer.

5‐Side bars: Torsion reinforcement values are taken from ETABS report. Side bars calculated according

to the share of side faces of beam divided by total perimeter (as in note 6‐iii).

This value is then increased by user increase factors. No minimum check reinforcement

check is performed on this value. Maximum spacing between bars is restricted to the

value specified by user in Settings page. Final bars shown in beam schedule are reported

for each face. For example 3‐T12 means each face (3‐T12 on left and 3‐T12 on right

face).

6‐Decimal places: Decimal places in Settings page affects all reinforcement values except shear Av/s

values.

7‐Printing: There are 3 options; FOR ENGINEER, FOR CAD and AREA REQUIRED. Clicking on each option

gives you print preview of only that portion. You can select print settings and print the

desired portion of beam schedule.

i) FOR ENGINEER portion has bar designation with reinforcement

values. Engineer can re‐check the bar dia based on the reinforcement

values.

ii) FOR CAD contains only bar designations. This option can be used to

give final print to CAD for final drawing beam schedule.

iii) AREA REQUIRED option gives you a comparison between area

provided and area required and the percentage difference. This can be

used later on after a project to check beam capacities for any changes.
