In order to launch Column Base, you must already have Windows running.

To launch ColumnBase

1. Click the Start button on the Windows Taskbar that appears along one edge of your Windows screen. A menu appears with various options.

Becomfamiliar wColumn B2. Click the Programs option. This will show another list or table of all the applications that are installed on your system.

4. Click the Column Base Design option to launch the application.

ingith

ase

In Column Base you always work on a P r o j e c t which can contain all the bases for a particular job1.

For each Project there are two distinct windows: the Project Workspace window which shows all the bases that the project

contains, the Report window which shows what your report will contain and how it will

look when printed. You can ensure that your report is complete before you print it, transfer it to TEDDS or to Microsoft Word.

1. Limited only by the memory and resources available on your computer.


For each Base in the project there are two distinct windows: The Base Plate Definition window shows a graphical representation of your

base plate. You can click on specific items to modify particular details quickly. The Design Summary property sheet shows the design results for the base

plate. It displays the status of each check and allows you to see particular results in more detail. If you have the automatic design option switched on, then the Design Summary will appear as soon as a design is possible, otherwise it will appear as soon as you choose the Design button.

Note If you open a project that you have saved to disc you will see the B a s e D e f i n i t i o n window for the first base plate in the

project. To see the results for the base plate you need to choose the De s i g n button. You can see the details for other base plates by selecting them from the P r o j e c t W o r k s p a c e .

An overview of the main Column Base window and each view follows (first for the base and then for the project). You will find more information on each view later in this User's Guide.

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 Column Base quickly and efficiently.

Column BasBase ics

Column Base is a powerful Windows based design and checking tool based on the requirements of the BCSA/ SCI publication Joints in Steel Construction, Column Base. Column Base integrates a range of tools for defining and checking a wide range of column bases of the types usually found in portal frame and multi-storey frame design.

Column Base is based around the concept of a P r o j e c t which can contain anything from a single column base to all the column bases required for a building1. many. You define the layout and loading for each column base (from scratch or by copying and modifying existing column bases). Once you have defined a column base you can design it.

1. Constrained only by the memory and resources available on your computer.

6. Finally specify whether the bottom of the column is to be Prepared for Direct Contact in Bearing.

If this box is checked then the axial force in the column is transferred directly from the column to the base plate. The welds are only nominal and simply hold the two parts together.

If the box is not checked then the welds are designed to transmit the force from the column into the base plate and will probably be much more substantial.

To definecolumn b7. Once your C o l u m n details are correct choose OK.

Caution Your column base definition is not yet complete. If you choose C a n c e l at this stage your new column base will not be created.

thease

1. When you define a new column base and click OK for the column details you continue to define the base using the Base Plate Details property sheet. The precise details for this sheet depend on whether you are defining a S i m p l e B a s e or a M o m e n t B a s e .

Note The property sheets for a moment base are shown in the following steps. The differences for simple bases are clearly indicated.

!


To define theBase Plate

The first stage in defining the base plate is to define the plate itself. 1. If you are defining a moment base, then you can position the column eccentrically on the base plate in the XX direction by entering the appropriate value for the Column Eccentricity. If you are defining a simple base, then the column must be positioned centrally on the base and so the eccentricity is dimmed.


Note You can only enter a positive eccentricity. If you would need to define a negative one, then you should define a mirror image of the base.

2. Set the Length of the plate by entering a value directly, or by choosing one of the standard lengths from the list.

3. Set the Width and Thickness in a similar manner.

4. Choose the type of Edge Preparation and Grade for your plate from the appropriate lists. Note When you choose the G ra d e C o l u m n B a s e will calculate the strength based on the base plate thickness.

5. Choose whether you want to use Adjustable or Non-adjustable bolts for this column base: Adjustable indicates that you are going to cast each foundation bolt in a

conical pocket which will allow some movement for the positioning of the base plate, the pockets being back filled with grout after the base plate has been positioned.

Non-adjustable indicates that the foundation bolts are going to be cast into the concrete base. This provides direct anchorage between the concrete of the base and the foundation bolts, removing the necessity for anchor plates. The disadvantage of this approach is that the positioning of the holding down bolts must be precise otherwise they will not match the location of the holes in the base plate.

6. Irrespective of the method of shear transfer that you choose you need to enter the Coefficient of Friction between the steel base plate and the concrete base.


Help Through P r e f e r e n c e s you can set the default Fr i c t i o n Co e f f i c i e n t , see To set base plate preferences on page 46.

7. Finally choose the method of Shear Transfer you want to use to transmit the shear force from the steel base plate into the concrete base and enter the appropriate details.

Note If you choose the Friction and Bearing on Bolts option for Adjustable bolts, then you can enter the Fa c t o r s used in calculating the bearing resistance of the bolts. The default

?values of zero mean that the bolts provide no bearing component, while the maximum values give the bolts the same bearing component as Non-adjustable bolts. You must ensure that the bolts in your completed base are able to provide the bearing resistance that you specify.

Note If you choose the Friction and Shear Key option, then you can enter the Le n g t h and De p t h of the shear key.

Help Through P r e f e r e n c e s you can set the default method of shear transfer, see To set base plate preferences on page 46.

8. Choose another page of the Base Plate Details property sheet or OK to save and create your base.

To define theBolt Layout

Now define the layout of the bolts.

Bolt Layout - Simple Base

3. Enter the End distance from the centre line of the outer or only row of bolts to the edge of the base plate.

Help Through P r e f e r e n c e s you can set the default end distance, see To set base plate preferences on page 46.

4. For two rows of bolts, enter the Gauge.

?5. Choose whether you want to define the position of the bolts across the base plate by giving the Pitch between them or by giving the Edge Distance that you want to use and then enter the appropriate value.

Help Through P r e f e r e n c e s you can set the default manner and distance, see To set base plate preferences on page 46.

6. The other parts of the page show the dimensional requirements you must meet for your base plate to be valid.


?


To define theBolts

The next stage in defining your base plate is to give the details of the bolts.


1. Set the size and type of bolt that you want to use by choosing the bolt icon ( ) to see the Data List - Bolt Data dialog. Choose the type of bolt and then choose its size. Once the correct type and size is shown choose Select to return to the Bolts Page.

2. Enter the Length and Clearance Hole Diameter for your foundation bolts.

3. If you want to change the position of a bolt across the base plate, select the line for that bolt in the Bolt Offset table, enter the new Y value and click on the Apply check box.



To defineConcrete

Base details

Now you can proceed to define the details for the concrete base. Column Base can handle the calculations for the concrete base whether or not you know its size: if you do not know the size of the base then Column Base assumes that the

entire punching shear perimeter can be accommodated within the confines of the base,

if you do know the size of the base then Column Base checks the punching shear perimeter and takes account of any part that lies outside the base.


1. If you do know the size of the base, then you should always choose Known and enter the base Length, Width and Depth, otherwise choose the Not known option.

2. Set the Concrete Grade for your base from the list of grades.

Help Through P r e f e r e n c e s you can set the default concrete grade, see To set concrete base preferences on page 51.

3. Choose the method you want to use to define the amount of Steel Reinforcement in the base and enter the appropriate details:

? Area Reinforcement allows you to enter an area of steel as a value in mm2.

Percentage Reinforcement allows you to enter the reinforcement as a percentage of the total area of the base.

Difference Simple bases do not contain any reinforcement.

Chapter 14 : Creating a report : 109

14 Creating a report When you complete your column base design(s) you may need to create a report. Its scope could range from brief details (sufficient to jog your memory if the design is to be taken further) through to a complete submission (ready to send to a checking authority or to your client). Column Base has a sophisticated report generator which allows you to produce high quality reports that contain exactly the level of detail that you require.

Caution If you I g n o re the problem then your report may not print correctly.

3. Paragraph Spacing allows you to set the amount of white space that you want to see between the paragraphs in your report. A larger amount of space will make your report look less cluttered, but will increase the number of pages.

4. By default Column Base numbers all reports starting at page one. If you want to create a series of reports numbering them sequentially, then print each one in turn and set the First Page Number for the current report to one greater than the last page of the previous one.

5. Many of the reports include tables of information. If you want the headers of the tables shaded, then check Table Background.
