STAAD.Pro is capable of performing design operations on specified members. Once an analysis has been performed, the program can select the most economical section, i.e., the lightest section, which fulfills the code requirements for the specified member. The section selected will be of the same type section as originally designated for the member being designed. Member selection can also be constrained by the parameters DMAX and DMIN, which limits the maximum and minimum depth of the members.
Member selection can be performed with all the types of steel sections with the same limitations as defined in Section 7C.7.
Selection of members, whose properties are originally input from a user created table, will be limited to sections in the user table.
Member selection cannot be performed on members whose section properties are input as prismatic or as the limitations specified in Section 7C.7.
