摘　　要：钢柱脚是承上启下的连接构件,优良的抗震性能尤为重要,利用大型有限元软件ABAQUS建立了边柱埋入式柱脚有限元模型,考虑材料非线性和几何非线性,分析了一个新型边柱埋入式柱脚试件在循环往复荷载作用下的抗震性能并对比了有限元结果和试验结果,两者吻合较好,该模型适用于钢结构边柱埋入式柱脚的抗震性能分析。The steel column foot is the connecting member with the upper and lower joints. The excellent seismic performance is particularly important. The large-scale finite element software ABAQUS is used to establish the finite element model of the embedded column foot column. Considering the material nonlinearity and geometric nonlinearity, a new type of analysis is analyzed. The seismic behavior of the side-column column specimens under cyclic loading and reciprocating loads is compared with the finite element results and experimental results. The two models are in good agreement. The model is suitable for the seismic behavior analysis of embedded columns of steel structure side columns.
