D3.E.1 Cross-Sectional Properties

You specify the geometry of the cross-section by selecting one of the section shape designations from the Gross Section Property Tables published in the "The Steel Construction Institute", (Design of Structures using Cold Formed Steel Sections).

The Tables are currently available for the following shapes:

  • Channel with Lips
  • Channel without Lips
  • Z with Lips
  • Pipe
  • Tube

Shape assignment may be done using the Properties - Whole Strucutre dialog of the graphical user interface (GUI) or by specifying the section designation symbol in the input file.

The properties listed in the tables are gross section properties. STAAD.Pro uses unreduced section properties in the structure analysis stage. Both unreduced and effective section properties are used in the design stage, as applicable.
