In STAAD Pro SS6 edition (Version 20.07.11.70) when a member subjected to Combined Axial force and bending, the member fails with higher ratios (i.e., 200, 216584 etc. ) according to section 126.96.36.199 as per IS 800 - 2007 (LSD). But when I calculate manually for the Axial force and Moment for the STAAD section forces using the equation,
As per IS 800 - 2007, Section 188.8.131.52
I get Lesser value of ratios. Kindly confirm me, STAAD Pro SS6 edition (Version 20.07.11.70) uses which formula, for calculating section strength ratio for steel member design for code IS 800 - 2007
STAAD.Pro V8i is not supported anymore. Please upgrade to the most recent STAAD.Pro CONNECT Edition and check if you are getting the expected design results.
