摘　　要：由于缺乏计算理论和方法,大多数半刚性节点按刚接或者铰接进行设计,对结构的抗震性能评估影响很大。文章在半刚性节点试验的基础上,采用有限元分析软件SAP2000对一个考虑梁柱半刚性节点的货架结构建立有限元模型并进行了模态分析和反应谱分析。结果表明,考虑梁柱半刚性连接的货架结构,其抗震性能明显变化。Lack of theory and method of calculation,most of the semi-rigid connections were designed as rigidity or hinged,which has great influence to the seismic performance.On the basis of an experiment to semi-rigid connections and the finite element analysis software SAP2000,this paper established finite element model to a storage rack which considering the semi-rigid connection,then made an analysis against its modal and response spectrum.The results show that there are significant changes in seismic performance of storage rack which concidering the semi-rigid connection.
