TR.20 Member Property Specification

This set of commands may be used for specification of section properties for frame members.

The options for assigning properties come under two broad categories:
  1. Those which are specified from built-in property tables supplied with the program, such as for steel, aluminum and timber.
  2. Those which are not assigned from built-in tables, but instead are specified on a project-specific basis, such as for concrete beams and columns, or custom-made sections for industrial structures.
