... motions on 22 steel moment frame building models with heights of 3, 9, and 20 stories. We find that if T 1 ≤ T ≤ 2 T 1 , Sa 70% ( T ) is efficient and usually sufficient for the considered levels of highly nonlinear response. Sa 70% (1.5 T 1 ) is generally an efficient choice. We find that Sa 70% ( T...
