M. To add a member specification

To add a specification for beam members in your model, use the following procedure.

Tip: As with most assignment options, you can select a set of objects prior to starting this procedure and make the assignments to this selection set by using the dialog's Assign button.

Member specifications are used to assign beam members as cables, truss, tension- or compression-only. Similarly, additional specifications for member end offsets, fireproofing, and inactive members can be assigned.

Select the Specifications page in the Analytical Modeling page control bar. The Specifications - Whole Structure dialog opens.
In the Specifications - Whole Structure dialog, click Beam. The Member Specification dialog opens.
Select the dialog tab corresponding to the member specification you want to add:
- Release
- Offset
- Property Reduction Factor
- Cable
- Truss
- Compression
- Tension
- Inactive
- Fire Proofing
- Imperfection
Note: Truss, Compression, Tension, and Inactive specifications have no additional parameters required. All other specifications require some additional input on the respective tab.

Either:

To…	Do the following…
add the specification to the model for later assignment	click Add.
add the specification to the model and assign to the current member selection	click Assign.

The dialog closes.

The member specification is added to the Specifications - Whole Structure dialog and the Specification Values table.

You can repeat this procedure as many times as necessary to add additional member specifications to your model.

If you did not assign the specification to a selection set, you must select the specification in the Specifications - Whole Structure dialog and assign it using one of the assignment methods.
