M. To assign axial action members
To assign a member as compression-only, tension-only, or a truss (axial-only) member, use the following procedure.
STAAD.Pro allows you to specify the axial actions of members.
Note: This assigns the analytical specification for truss members. For the purpose of
Connection Design, you must additionally assign a Truss
attribute.
