D. TS500 Column Design Brief dialog

The TS-500 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, fck, (in N/mm2).

Specify the maximum aggregate size. (in mm)

Specify the cover to the shear reinforcement. (in mm)

Available concrete grades include: C20, C25, C30, C35, C40, C45 and C50

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.

Available steel grades include: S220a, S420a and S500a.

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.

Select whether for circular columns either 'Tie' or Spiral' reinforcement should be used.

Available steel grades include: S220a, S420a and S500a

Include Seismic Checks Select this option to include additional checks
Note: Unless stated otherwise, the available bar sizes include: 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50

Column Factors tab

SettingDescription
Slenderness Factors This may be set to 1, or calculated by the design.

Specify 'Creep coefficient'

For long term loads, specify 'Longitudinal Force' (in kN) and 'First order moment' (in kNm)

Bracing Conditions in both local y-y and z-z directions.

Specify the effective length factors to be used.

Select whether or not the local axis is braced, and if not, the value of stability Index Q to use.

Select the load case to be used for Sidesway or use the same as the design load case.

Include Torsion Effects Select this option to include torsion effects.
Design as Sway Frame Select this option to Design as Sway Frame.
Biaxial β factor Specify the value for the biaxial beta factor.
Rm Specify the value for the R(m) factor.
Starter Bar Area Provided 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.
