Node is the key parts of frame structure, and has important influence in load-carrying capability. Using FEM software ABAQUS, based on the experimental result of beam-column joints of existing steel anchor foot, the paper compared and studied the failure mode and shear behavior of steel concrete beam-angle concrete column joint, steel concrete beam-reinforced concrete column joint and steel concrete beam-column joint, and made parametric analysis on steel concrete beam-angel iron concrete column joint, and observe and study the influence of axial load ratio no, steel beam thickness tw, angel iron steel ratio pa, stirrup reinforcement ratio of joint core pv, concrete strength fc, on joint shear behavior.%节点为框架结构的关键部位,对结构受力有重要的影响.采用有限元软件ABAQUS,在已有型钢锚脚的梁柱节点试验结果的基础上,对比研究了型钢混凝土梁-角钢混凝土柱节点、型钢混凝土梁-钢筋混凝土柱节点和型钢混凝土梁柱节点的破坏模式及抗剪性能；对型钢混凝土梁-角钢混凝土柱节点进行参数分析,考察了轴压比n0、型钢腹板厚度tw、角钢配钢率ρa、节点核心区配箍率ρv、混凝土强度fc对节点受剪性能的影响.
