Space frame problem
Space frame problem
(OP)
Hello everybody
I m doing a model of 1-floor reinforced concrete space frame with concrete slab. I m using columns 100x100cm (C70/85), beams 45/90cm (C50/60) and 22cm thick slab (C35/45). I m doing elastic analysis for only selfwight load. Results along with my staad file are in attachments. Problem is that sagging (vertical deflection) on 4 corner edges of my model is to big -node displacement around 11mm and it sholud be around zero, because of the columns!

Can anyone tell me what is the problem? Static check is ok, forcess in columns seems ok too. I m using staad pro 2007. Its urgent. Thank you.
