D8.C.1 Cross-Sectional Properties
The AISI Design Manual has been followed to calculate section properties (e.g., Cw) which are not available in the Indian Standard and Manual.
Checks per IS 801 are supported for the following profile shapes:
- Angle with lips
- Channel with Lips
- Channel (or eave strut)
- Zee or zee purlin
- Zee with lips
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.
