Re: STAAD Results interpretation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I found a major error last year in Staad III. We were designing a concrete
tank basin with 60'0"" girders whereby large Torques were present on the
girder from out of plane wind. I had 15 different load cases and the the
stirrup design stopped on the first load case and did not check the other
14. We reported this to Staad III and so far to the best of my knowledge
they have not fixed it.
