本文用算例按基底剪力法、振型分解反应谱法和时程分析法分别分析了多层基础隔震钢结构和多层钢筋混凝土结构及其对应的非隔震结构的地震力和层间剪力。多层基础隔震钢结构与多层基础隔震钢筋混凝土结构相比， 其各层的层间刚度较小， 隔震结构与对应的非隔震结构的第一自振周期之比较小， 但其隔震效果仍较显著
In this paper, the seismic forces and layers of multi-story base-isolated steel structures and multi-story reinforced concrete structures and their corresponding non-isolated structures are analyzed by means of base shear method, mode-decomposition response spectrum method and time history analysis method. Interval shear. Compared with multi-story base-isolated reinforced concrete structures, multi-story base-isolated steel structures have smaller interlaminar stiffnesses, and the first natural vibration period of isolated structures and corresponding non-isolated structures is relatively small, but Its isolation effect is still significant
