D. AS 3600 Column Design Brief dialog

The AS 3600 Column Design Brief has the following tabs for setting out the design parameters:

General tab

SettingDescription
Concrete

Specify the concrete strength either from the available concrete grades or by defining a concrete strength, fcu, (in N/mm2).

Specify the minimum center to center spacing for reinforcement.

Specify the cover to the shear reinforcement.

Main Bars

Specify the strength of steel to be used for the main bars either from the available steel grades or by specifying the steel yield strength to be used. If a user strength is defined, then the appropriate bar bending dimensions need to be specified.

Specify the minimum and maximum bar sizes to be used.

Click the Bending Dimensions… button to open the Bending Dimensions dialog, which is used to specify bending dimensions for each bar size.

Links

Specify the strength of steel to be used for the shear reinforcement bars either from the available steel grades or by specifying the steel yield strength to be used.  If a user strength is defined, then the appropriate bar bending dimensions need to be specified.

Specify the minimum bar size to be used from 6, 8, 12, 16 or 20.

Click the Bending Dimensions… button to open the Bending Dimensions dialog, which is used to specify bending dimensions for each bar size.

Note: Unless stated otherwise, the available bar sizes include: 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50

Column Factors tab

SettingDescription
Bracing Conditions Specify whether the columns are braced in the local y-y and/or z-z directions.
Effective Length Factors Specify the effective length factors to be used in the local y-y and z-z directions.
Slenderness Limits This may be set to 1 (unity), or calculated by the design.
Area provided by starter bars Specify the area of starter bar steel (in mm2) to ensure that maximum area of steel is not exceeded by the design.

Member Loadcases tab

Used to select load case results which are used for column design with this brief.

SettingDescription
Available list Contains all primary load cases and load combinations in the STAAD.Pro input file.
Selected list

Load cases and combinations the results of which will be used for the column design when this brief is used in a Design Group.

Tool icon Description
> Adds the load case(s) selected in the Available list to the Selected list.
>> Adds all load cases from the Available list to the Selected list.
< Removes the selected load case(s) from the Selected list.
<< Removes all load case(s) from the Selected list.
Note: By default, no load cases or combinations are selected.
SettingDescription
OK Accepts parameters on all dialog tabs and closes the dialog.
Cancel Closes the dialog without saving any changes.
Apply Saves changes made in the dialog. Only available if changes have been made.
