Good day I have modeled a structural steel frame building and analyzed it using the direct analysis method, however I have received a few warnings and I would like to know the relevant of these as well as their potential effect on my analysis results…

I recently ran a fairly basic 3D steel frame analysis and design problem in STAAD. Members were grouped and SELECTed and then CODE CHECKed. I know that the SRF for LRFD3 is 0.85 and for AISC UNIFIED is 0.9. The design results from both runs is similar…
