Selecting Assign > Frame Types opens the Assign Frame Types dialog. From this dialog, the engineer can assign frame types to all the Lateral Steel members. The engineer must assign a Frame Type before a Code Check can be performed. The engineer should assign a frame type to all the members of the frame. For example, the concentric frame designation should be assigned to the beams, columns and the braces of a concentric braced frame. If the engineer does not want the program to check an individual member then the member should have no type assigned to it. Note that the available frame types are dependent on the selected seismic provisions code. Note that the EBF frame type is only available if AISC 1997, AISC 2002, or AISC341-05 is the selected seismic code. A member code check can be performed for frame type BRB and BRB-V when a Star Seismic^® or CoreBrace^® BRB size is assigned. Frame types OCCS and SCCS are only available if AISC 341-10 or AISC 341-16 is the selected seismic code.

After the appropriate frame type is selected from the dialog the engineer can assign the criteria to a single member (click on Single) or to multiple members (click on Fence). If Single is clicked the dialog will close and a target cursor will be made available. Click on each section to assign the frame type to. If Fence is clicked the dialog will close and a fence cursor will be made available. Click-and-drag a rectangle around all the members to assign the frame type to.

To view member frame types select the appropriate option from the View-Members Dialog. If a frame type is assigned and then the seismic code is changed, all frame types not valid in the new seismic code will appear with a line drawn through the name.
