Design Code

Use this function to select the design code to apply for the strength verification of steel members and specify the lateral bracing condition of the structure's horizontal members (beams and girders).

From the Main Menu select Design > Steel Design Parameter > Design Code.

From the Menu tab of the Tree Menu select Design > Steel Design Parameter > Design Code.

The following dialog box is used for data entry:

Note 2
When the top compression flanges of the steel girders or beams are connected to the concrete floor by welded metal decks and/or shear connectors, it is assumed that all the members are laterally braced. If this item is selected, the Laterally Unbraced Length (Lb) field is deactivated in the "Unbraced Length (L,Lb)" Dialog Bar and Lb = 0 is applied to all the members.
(Refer to "Unbraced Length (L,Lb)")
