Truss members can either be defined manually, or the process can be automated using the Truss Wizard. Irrespective of the method used, the resulting Truss members will be one of four types:

Depending on the type, different design procedures are adopted.

Internal and side truss members

The design checks for internal and side truss members are the same as those for braces. With the exception that seismic forces are not designed for. See: Steel brace design to AISC 360

Top and bottom truss members

The design checks for top and bottom truss members are the same as those for beams. With the exception that seismic forces are not designed for. See: Steel beam design to AISC 360
