Dear friend,
I am currently designing dynamic analysis for recriprocating compressor. Dynamic load for this machine consist of horizontal load, vertical load, horizontal couple and vertical couple. Recriprocating compressor is supported by concrete block foundation which is modeled as slab. The output of this analysis show that horizontal/vertical couple (dynamic load) did’nt impact anything to amplitude displacement.
I’d like to know why this situation could occurred? Could slab model could not transfer couple load?
Also I attach my STAAD model.
Thank you for your help.
