Dear Sir,
I make a steel roof structure supported by concrete columns. 1 side supports are pinned other side supports having a release to avoid temperature effect.
When I run a staad model without concrete columns it's safe but when I added concrete columns and provide same releases on the top it's showing some problems.
Please check both staad file and advise me.communities.bentley.com/.../CINEMA-ROGH.stdcommunities.bentley.com/.../CINEMA.std
