摘　　要：针对已经完成的柱脚采用半刚接自复位装配式钢框架1层子结构(原模型为4层)进行拟动力试验,采用ABAQUS有限元分析软件建立4层单跨有限元模型进行动力时程分析,分析钢框架的位移响应、开口变化、滞回曲线和各部位的应变发展状况,并与试验结果进行对比分析。分析结果表明:有限元和试验结果较为吻合,证明了半刚接自复位钢框架的优越性和有限元分析的可靠性,为今后进一步开展研究打下良好的基础。Basing on the pseudo dynamic test on self-centering prefabricated steel frame with semi-rigid column base,the ABAQUS finite element software were utilized to establish the four layers of single-span finite element model for dynamic time-history analysis,to investigate the displacement response,gap opening,hysteretic curve and strain development,while compared with the test structure analysis. The analysis result showed that the simulation results agreed with the test results,improved the advantage of self-centering prefabricated steel frame with semi-rigid column base and reliability of finite element analysis,which lay the better foundation for the further study.
