摘　　要：在已有钢连梁埋入混凝土剪力墙节点试验的基础上,通过ANSYS有限元模拟结果与已有试验结果的对比分析,验证了有限元模拟的可靠性;通过6组不同参数下的钢连梁埋入混凝土剪力墙节点有限元模型,分析了剪力墙混凝土强度、墙体配筋率、墙体轴压比、钢梁高度、钢梁翼缘宽度、钢梁埋置深度对该种节点在弯矩剪力共同作用下发生承压破坏对应的承载力的影响,得出了定性结果。Based on previous experiments , the reliability of the joint finite element model was verified by comparing its simulation results with the experimental results .Six factors that affect the moment-shear com-pression bearing capacity of the joints , which result in bearing failure finally , include concrete strength , rein-forcement ratio , axial compression ratio , steel beam height , steel flange width , and embedded depth of the steel beam , were quantitatively analyzed .Some quantitative results were obtained .
