摘　　要： 基于纤维模型和动力相似理论,利用ETABS和PERFORM-3D分析软件对一缩尺比例为1/8的平面三层型钢混凝土框架结构进行了整体结构弹性、弹塑性分析和推覆分析。将所得动力响应值与振动台试验实测结果进行对比,验证了8度小震、中震、大震作用下结构的抗震能力,研究结果表明型钢混凝土结构具有较大的水平抗侧刚度及弹塑性分析软件PERFORM-3D适用于模拟振动台结构模型的抗震性能分析。 Based on fiber element model and the law of dynamic similarity,the SR C-frame model,a three-story plane model with the scale factor of 1/8,was creat ed by ETABS and PERFORM-3D software.Analysis of the whole structure model,whic h included elastic time history analysis,elastic-plastic time history analysis and push-over analysis,was applied by the ETABS and PERFORM-3D software.This p aper compared dynamic response of different earthquake actions between the numer ical simulatation analysis results and the experimental results of shaking table test.The comparison confirmed the seismic capacity of the structure model unde r frequent,moderate and rare earthquake in this paper.So the study indicated t hat the SRC-frame had a large horizontal level stiffness and PERFORM-3D software was suitable to simulate the seismic performance analysis of model of shaking t able test.
