摘要

为研究复杂结构的抗震性能,进行了一幢钢框架-支撑结构体系1/20缩尺模型的地震振动台试验,试验测试了模型结构的动力性能和结构地震反应.同时,利用ANSYS软件建立了有限元分析模型,并对试验模型结构进行了动力弹塑性时程分析,就模型的频率、位移反应和应变反应进行了对比,计算结果和试验结果吻合较好,验证了有限元模型的可靠性.
The shaking table test of a 1/20 scale model with steel frame-bracing system is performed to study the seismic behavior of complex structure in this paper.In the shaking table test,the seismic responses and dynamic characteristics of the structure are measured.Furthermore,the structural finite element analysis model is established with ANSYS software,and then the elasto-plastic time-history analysis of the shaking table test model is carried out.The analytical results of structure periods,displacement response and strain response are in good agreement with the test results,which verifies the reliability of finite element model.
