Sir,
A test facility consist of a 2 floor steel structure and on the steel structure a box type steel structure (tank like) is mounted on its 2nd floor (top floor) for some components testing.
My requirement is to qualify the steel structure for seismic load.
My doubt is while doing the seismic analysis of steel structure whether i need to model the box type structure also in the model and do the analysis??
Pls. suggest some idea for simplifying my analysis ???
Waiting for your valuable suggestions.
Regards
Nir
