THE MODEL DEFORMS LATERALLY UNDER DEAD CASE !
THE MODEL DEFORMS LATERALLY UNDER DEAD CASE !
(OP)
Hi all
I have modeled a building of 4 stories and before defining load combinations and lateral load patterns ,the model behave normally under dead load, after defining earthquake patterns it deforms excessively in x and y...
I have attached a shot of deformed shape under Dead case, I would appreciate your opinions

Are you missing a support perhaps?

I'd try this:
1. Delete the earthquake load pattern.
2. Run the dead load case and write down the X and Y displacements at the center of the roof.
3. Add the earthquake load pattern.
4. Repeat #2.
