Hi,
My company is working on a steel structure analysis model that is giving us very unusual results when we change some WWF550x420 members to standard rolled shapes.
For example, if we change the WWF550's to W610x262's the model's utilization ratios blow up all over the structure (ratios that are more than 10 and much higher!) and for some members the "member design fails".
The other member far away from this area should not be failing because of a column size change. It looks very unusual and we cant figure out why it is doing this. Please help!
We are running STAAD Connect V22 Update 3.
Thanks!
