Hi,
Good day.
May I have your thoughts with regards to the design of the gravity frames that are not part of Seismic-Force-Resisting System. The building is a five-story office building located in high seismic area. The lateral load resisting system is Special Concentric Steel Braced Frame along the perimeter of the building and the interior steel frames are gravity load resisting frame only. The structure has been modeled in ETABS where the girders of gravity frames are modelled as pinned at both ends.
My questions:
1. Should the gravity steel frames be designed based on deformation compatibility. If so, should NSP (Nonlinear Static Procedure) will suffice.
2. In line with item 1, is there an alternative design procedure so as to avoid NSP procedure?
2. Should the girders and columns of gravity frames conforming to seismically compact elements?
3. Are there any references or design guides in the design and detailing of gravity frames located in high seismic area?
Thank you very much.
