The member selection process involves determination of the least weight member that PASSes the code checking procedure based on the forces and moments of the most recent analysis. The section selected will be of the same type as that specified initially.

For example, a member specified initially as a channel will have a channel selected for it. Selection of members whose properties are originally provided from a user table will be limited to sections in the user table. Member selection cannot be performed on members listed as PRISMATIC.

Refer to D1.B.1.4 Member Selection for general information on Member Selection. Refer to TR.49.1 Member Selection Specification for details the specification of the Member Selection command.
