Chapter 3 : Starting to use Crane Beam : 15

3 Starting to use Crane Beam

Becomingfamiliar withCrane Beam

In Crane Beam you always work on a P r o j e c t . Each P r o j e c t can contain all the crane beams for a particular job (limited only by the memory and resources available on your computer). You can open as many projects as you like (again limited only by the memory and resources) into Crane Beam.

When you launch Crane Beam and open a project, then you will see the Project

Workspace window. This shows you all the projects that you have opened and the crane beams that you have defined within them. The Project Workspace allows you to manipulate (copy, rename, edit or delete) those crane beams at will. The Project Workspace also allows you to open any crane beam Definition windows that you have closed for any reason.

For each P r o j e c t there is also a Report window which shows you the information that will be included in the output exactly as it will appear on the printed page. You can therefore ensure that the information you need is included in the report before printing it, transferring it to TEDDS or transferring it to Microsoft Word.

For each C r a n e B e a m in the project there are two distinct windows: the Definition window (which appears for every crane beam), is the one you

use to define the various parts of the crane beam, and where you see a graphical representation showing the items you have defined.

The Results Viewer which appears as soon as you have defined the crane beam in sufficient detail (if auto design is switched on) or when you choose to perform the design. This viewer (the Design Summary Property Sheet) indicates the status of the design as it stands at the moment and allows you to see particular results in more detail.


Note If you save a project to disc all the crane beam definitions and results are stored with it. However, when you recall the project, you will only see the D e f i n i t i o n windows. This approach is used in order to reduce screen clutter. However if you click the To o l ba r De s i g n I c o n or select the D e s i g n /De s i g n C ra n e B e a m menu option for any definition window, then this shows you the D e s i g n S u m m a r y P r o p e r t y S h e e t for that crane beam without performing a redesign.

If you are a first time user it is a good idea to take a few seconds to acquaint yourself with each of these views. Familiarise yourself with the terms and

concepts introduced in the following sections before you start using the application, such familiarisation will reward you in the long run, because you will be able to use Crane Beam quickly and efficiently.

An overview of the main Crane Beam window and each of the views is outlined below, further information on each view is covered in more depth in the later parts of this Users Guide.

Project WorkspWinacedow

Shows all the crane beams in your current project.


Design Summary The Design Summary gives you an overview of the design, and then allows you to access the different checks in more detail. The summary appears when you choose to perform the design. The summary shows you the individual checks that have been performed on the crane beam.

You can view the individual design checks for the crane beam in more detail by picking the appropriate tab from the top of the Design Summary property sheet or by double clicking the Design Condition.


The analysis resultswindow

This view shows you the results of the analysis of the current crane beam. A representation of a typical analysis is shown below. Note The values have been removed from the above diagram for clarity. They can be added as and when you choose.

You can choose the loading condition which is shown in the window by selecting it from the Loading and Analysis toolbar.


The report window This view shows you the calculations that have been performed for all the crane beams in the current project, exactly as they will appear on the printed page. You can also tailor the content of the report ensuring that it meets your particular requirements. A representation of a typical report is shown below.

Status Bar This shows information which relates to the status of the current connection definition and design in Crane Beam.


If you select a menu option, then the status bar gives one line of help information telling you exactly what the effect of that menu option will be.

Crane BeToolbamars

There are six toolbars available in Crane Beam: the Standard toolbar, the Beam, Loading, Design toolbar, the Beam Details View toolbar, the View toolbar, the Report toolbar, the Loading and Analysis toolbar,


These toolbars allow you to access many of Crane Beams features directly, instead of having to select them from the menus.

All the toolbars operate in a similar manner: they all contain tool icons that you choose to access particular features, they can all be placed wherever you like on the screen, they can all be switched on or off at will, you can choose the number of rows and columns which are used to display

the I c o n s that the toolbar contains, You can dock any Toolbar against the edge of the main Crane Beam window.

Chapter 4 : Understanding Crane Beam : 39

4 Understanding Crane Beam Crane Beam is an extremely advanced product, using state of the art Windows techniques, combined with CSCs years of experience in the design of structures to enable you to achieve extremely competitive solutions easily. At CSC we are rightly proud of this application, and hope that it will increase your productivity, while at the same time making your work more enjoyable.

Crane Beam Basics

Crane Beam is a powerful Windows based design and checking tool for defining and checking a wide range of crane beams.

Crane Beam adheres to Microsoft Windows conventions and to the standard CSC dialog style guide. This means that the operation of this application will be similar to the operation of all other CSC design applications. You can therefore get on with performing your designs, rather than worrying about how the program works.

As with any advanced application it is necessary to familiarise yourself with the terminology that is used, and some fundamental concepts. Taking the time to understand these now will amply reward you with increased productivity later.

Projects Crane Beam is based around the concept of a P r o j e c t . This project may contain a single crane beam, or it may contain many. You define the layout and loading for each crane beam that you need (creating them from scratch or copying previously defined crane beams and amending them as necessary).

Once this layout and loading is defined you can perform a complete check of the crane beam for adequacy under all the appropriate conditions.

Chapter 5 : Setting preferences : 40

5 Setting preferences

Understandingpreferences

Crane Beam allows you to set a range of P r e f e r e n c e s which control the way that it works. These preferences allow you to control the default values that Crane Beam will propose for the various items of information that you must provide in order to define your crane beam.

Obviously if some of the input has been automatically generated for you,

Settpreferences

Crane Becorrectly, in this way, then it will take you less time to define a crane beam than if you had to enter all the values yourself.

Note If any of the values proposed by C r a n e B e a m (based on your preferences) are not suitable for a particular crane beam, then you can simply replace the default value with the correct value for this particular case.

ing foram

When you first start Crane Beam you will find that preferences are already set. If you want to change these, then you do so at any stage.

Note You can change your preferences as often as you like.

You use colour preferences to control the colour of the various parts of the graphical connection display.

For a solid display the colour you choose is the base colour for that part of the connection, however this will be affected by the lighting to give you a rendered 3-dimensional view of the beam.


For a wire frame view (i.e. when you are panning or rotating the display) the colour you choose is the colour of the lines used for that part of the beam.

1. Select File/Preferences

You will see the Preferences property sheet showing the Units page. Pick the Colours tab. The colour swatch to the side of each component shows the base colour that will be used for that component.

2.

Chapter 7 : Manipulating the Beam Definition graphical display : 56

7 Manipulating the Beam Definition graphical display When you create a beam and define its length, or if you change to a different standard view orientation the Beam Definition window will show the beam at a scale which causes it to fill the window. For many beams this display will be adequate for you to pick major elements. However for very large beams the display may be too small for you to do this efficiently.

8 Defining a Crane Beam

Defining a newproject

When you first start Crane Beam, you will see the Crane Beam window and the Crane Beam splash screen. After a few seconds the splash screen is removed, leaving you with a Crane Beam window which is, initially, empty.


Crane Beam allows you to define as many crane beams as you like (subject only to memory and resources available on your computer). However each crane beam must be included in a project. Therefore until you create or open a project Crane Beam does not allow you to define any crane beams.

You must therefore either decide whether you want to create a new project or open an existing project to work on.

At this stage we shall only consider the steps required to create a new project.

the Guide Roller Dimension the dimension out from the external wheels of the bogey to any guide rollers that are present. This information is only applicable to C l a s s Q 3 or C l a s s Q 4 cranes. If the bogeys are on a pivot system, then you can specify a negative value for the Guide Roller Dimension to decrease the distance for the crabbing couple to that between the pivot points.



To define therail details

1. Click the Rail icon and you will see the Beam Properties sheet which will be open at the Rail tab. 2. Select the Profile that you want to use from the list of available profiles.

3. Select the Size that you want to use from the list of available sizes.

Note The available S i z e s depend on the Pro f i l e type that you select.

C r a n e B e a m shows the Properties of the rail for your convenience, you cannot change these.



To define thewheel loads

1. Click the Wheel Loads icon and you will see the Beam Properties sheet which will be open at the Wheel Loads tab. When you access this page you will see that Crane Beam has already calculated the wheel loads for you based on a two wheel bogey.

2. If your crane has more than two wheels, and you want to add a new wheel to the end of the list click Add. If you want to add a new wheel above the current row in the table click Insert.


3. Crane Beam will calculate the wheel loads based on the crane details and number of wheels which you have defined. If you have details of the wheel loads as part of the manufacturers data and these are different to the automatically calculated values tick Override and enter the wheel loads directly.

Note The value which you need to enter for the H o r i z o n t a l Loa d is the value of the vertical load to which the appropriate factor is to be applied to calculate the horizontal forces acting longitudinally and transverse to the crane rail. Note If you are defining a crane of class Q3 or Q4, then the dialog will reconfigure to allow you to define the crabbing load.

4. If the default Wheel Centres (0.5 m) are not correct, then enter the Wheel Centres which you want to use.

Note The default value of 0.5 m allow for the closest approach of a pair of wheels when 2 cranes are acting in tandem. If this condition does not arise in your configuration, then for ordinary wheel loads the minimum Wheel Centres that you define should be the crane span/7.

5. For the impact condition enter the Impact percentage by which the Static crane loads are to be increased for the impact condition.


Example If you have a static wheel load of 100 kN and you specify an impact percentage of 25%, then the load taken for the impact condition will be 125 kN.

6. Enter the percentage of the vertical load which you want to take for the Longitudinal surge force acting horizontally on the crane rail.

Example If you have a static wheel load of 100 kN and you specify a longitudinal surge percentage of 5%, then the load taken for the longitudinal surge condition will be 5 kN.

E

E7. Enter the percentage of the vertical load which you want to take for the Transverse horizontal surge force acting on the crane rail.

Example If you have a static wheel load of 100 kN and you specify a transverse surge percentage of 10%, then the load taken for the transverse surge condition will be 10 kN.

8. For the transverse surge force specify whether the entire force is to be taken on one crane beam, or whether the transverse surge force is to be shared equally between both crane beams (at either end of the crane).

Note The s u rg e s h a re d e q u a l l y b e t we e n b o t h c ra n e b e a m s setting does not apply to crabbing loads which are always taken on one beam within the critical combination

To define thebearing

details

1. Click the Bearing Data icon and you will see the Beam Properties sheet which will be open at the Bearing tab. If your crane beam has only one span, then the internal bearing details will be removed from the page since they are not appropriate.


2. If you want to specify the details of the bracket which supports the end of the crane beam, then you need to define the Bracket Size. Click Bracket Size to indicate that this is the method you want to use to determine the bearing length and then click Select and you will see the Data List for I sections. 3. From the Data List pick the Section Type (from the left pane) and the Section Size (from the right pane). When you have made your selection click Select to return the chosen section to the Beam Properties sheet.

Note C r a n e B e a m assumes that the bracket is unstiffened. If you want to use a stiffened bracket, then you should calculate the stiff bearing length yourself and use the Length b1 method to specify the length which you have calculated.

4. If you prefer you can enter the stiff bearing Length b1 for the crane beam support directly. Click Length b1 and then enter the Length that you want to use directly.


5. You use the Beam Clearance to define the distance from the end of the beam to the centre-line of the bracket. There are two possible conditions as shown below:

there is another crane beam connecting to the same bracket. If so, then the distance which you specify here should be half the distance between the two adjacent beams.

Beam ClearanceBeam Clearance


there is no other crane beam on the other side of the bracket. In this case you can specify a positive value (as above) or you can specify a negative value in which case this will allow the crane beam to sail over the bracket/stiff bearing length developing an increased bearing resistance.

Beam Clearance


6. If you want to specify the details of the bracket which supports the crane beam internally, then you need to define the Bracket Size. Click Bracket Size to indicate that this is the method you want to use to determine the bearing length and then click Select and you will see the Data List for I sections. 7. From the Data List pick the Section Type (from the left pane) and the Section Size (from the right pane). When you have made your selection click Select to return the chosen section to the Beam Properties sheet.

Note C r a n e B e a m assumes that the bracket is unstiffened. If you want to use a stiffened bracket, then you should calculate the stiff bearing length yourself and use the Length b1 method to specify the length which you have calculated.


8. If you prefer you can enter the stiff bearing Length b1 for the crane beam support directly. Click Length b1 and then enter the Length that you want to use directly.


To defineother design

needs

1. Click the Design Data icon and you will see the Beam Properties sheet which will be open at the Design tab.


2. Enter the Partial safety factors that you want to use: the Vertical (Static or Impact) + Horizontal loads considered

separately (Gammaf) factor is used when Crane Beam checks your vertical and horizontal loads acting separately,

the Vertical Impact + Horizontal loads combined (Gammaf) factor is used when Crane Beam checks your vertical impact and horizontal loads acting together,

the Vertical Static + Horizontal loads combined (Gammaf) factor is used when Crane Beam checks your vertical static and horizontal loads acting together. . If your crane beam has only one span, then the internal bearing details will be removed from the page since they are not appropriate.

3. Enter the Vertical deflection limit as a ratio of the span of the beam.

Example If you have a six metre long beam and specify a value of 600, then C r a n e B e a m will apply a limit of 13.333 mm and will flag you if this limit is exceeded.

4. Enter the Horizontal deflection limit as a ratio of the span of the beam.

Example If you have a six metre long beam and specify a value of 500, then C r a n e B e a m will apply a limit of 12 mm and will flag you if this limit is exceeded.

Note Deflection limits for crane beams are usually far more rigorous than those for other members. Horizontal deflections are even more critical than vertical ones since excessive deflection could lead to the crane leaving the rails. The default limit is span/500.

5. If the Flange of your crane beam is restrained against rotation relative to the web, then leave its box ticked. If this is not true, then remove the tick and enter the Effective length factor, ke that you want Crane Beam to use when it checks the buckling capacity of the web.


To define welds The Welds page is only applicable if your crane beam is fabricated either from a beam and channel or of a beam and plate. It allows you to define the weld that connects these two separate parts of the beam.


1. Click any of the icons which access the Beam Properties sheet and then click on the Weld tab. 2. The only Type of weld which is applicable for a fabricated crane beam is a fillet weld, so the buttons for the other types of weld are dimmed.

3. Enter the Strength and Leg Length of the weld you want to use. The Preparation Length is not applicable for fillet welds and so is dimmed.



This completes the definition of your crane beam. Your Project Workspace will now show the crane beam that you have defined and you will see a window containing a graphical representation of it. This window will have the reference that you gave to the crane beam as its title.
