I am trying to get STAAD to check a non-standard C-shaped section with no lips. I have input the section properties into the section Database manager. See attached pdf.
Can STAAD do an accurate design check per the AISI code on a section that is manually input into the section database?
I ran a simple STAAD model with the section doing a fixed cantilever support with 100 lbs applied at 24 inches producing a reaction moment of 2,400 lb-in. The load is applied in the weak axis. The section modulus Sy = 0.287 in^3.
This section produces an design check ratio in STAAD of 0.605. When I compare this with a spread sheet I am only coming up with a design check ratio of 0.47.
Please see the attached STAAD file.
