摘　　要：针对钢梁-混凝土墙节点的抗震性能研究,节点采用刚性连接为分析对象。混凝土采用损伤塑性模型,型钢与钢筋采用三折线模型。并采用非线性有限元分析该类节点在低周反复荷载作用下的承载力。将分析结果与试验结果进行对比,验算有限元模型的有效性。并对其进行参数分析,分析不同螺栓直径和钢梁高跨比对节点抗震性能的影响规律。研究结果表明:随着螺栓直径的增加,节点的抗震性能都增加;随着钢梁高跨比的增加,节点的承载力也明显的增加。Studies on the seismic performance of steel beam and concrete wall node were carried out based on the rigid connection node as analysis object.Steel and concrete uses the damage plasticity model, reinforced by three line model.Nonlinear finite element analysis was used to analyze bearing capacity of thus node under low reversed cyclic load .By comparison of the analysis results with the test results, calculation of the finite element model is effective.And the parameter analysis was carried on,the influence law of different bolt diameter and beam depth-span ratio on node seismic performance was researched.The results show that with the increase of the bolt diameter, the seismic behavior of the node is increased;with the increase of steel beam depth-span ratio, the increase of the bearing capacity of node is also obvious.
