摘　　要：利用ABAQUS建立了4组不同参数下钢梁埋入混凝土剪力墙节点的有限元模型,分析了剪力墙轴压比、钢梁高度、钢梁埋入混凝土剪力墙长度、钢梁在不同的弯矩和剪力组合作用下对该节点承载力的影响。结果表明,随着轴压比的增大,节点承载能力降低;在一定范围内,随钢梁高度和埋入长度的增加节点承载能力提高;节点承压破坏时,所能承受的弯矩越大,则抗剪承载力越小,弯矩和剪力之间呈现负相关性。Four factors that affect the compression bearing capacity of the joints, which result in bearing failure finally, are axial compression ratio, steel beam height, embedded depth of the steel beam and the mutual action of moment and shear. Detailed analyses of joint compression bearing capacity by using the software, ABAQUS, were introduced in this manuscript. The results showed that with the increasing of axial compression ratio, the bearing capacity of the joints decreases. It is also indicted that with the increasing of steel beam height and embedded depth of the steel beam, the beating capacity of the joints increases in a certain range. However, it was observed that the greater of the bending bearing capacity, the smaller of the shear capacity.
