EXCESS STRESS AT FOUNDATION STUB COLUMN DUE TO THERMAL LOAD

EXCESS STRESS AT FOUNDATION STUB COLUMN DUE TO THERMAL LOAD

EXCESS STRESS AT FOUNDATION STUB COLUMN DUE TO THERMAL LOAD

(OP)
I am using temperature load as 35 Deg(TEMP 35 MEMB ALL). But it produces huge stresses at foundation in Fx & Fy direction. I reduced this by giving weak spring (10 Kn/mm) at Fx & Fy. I am using M27 anchor bolt and Hole dia is 40 mm. So 6.5mm gap will there all around bolt. Now my concerns is how could I achieve this 10Kn/mm spring action at this foundation.

You might want to post this along with your model on the Bentley hosted STAAD forum. https://communities.bentley.com/products/ram-staad...
I assume the original high stress was a result of overly constraining the model while applying thermal load.
