摘　　要：基于ABAQUS平台对比分析了3种节点模型的承载力及受力性能:①配置型钢锚脚的型钢混凝土梁-钢筋混凝土柱边节点;②型钢混凝土梁柱边节点;③配置型钢锚脚的型钢混凝土梁-角钢混凝土柱边节点,并对节点③开展参数分析.结果表明:角钢将对节点核心区混凝土产生约束作用,增大节点抗剪承载力,同时基于大量参数分析结果给出了节点③的抗剪承载力计算公式.This paper conducts a research on shear capacity and performance for three kinds of joints based on the platform of ABAQUS, e. g. , of steel reinforced concrete beam and reinforced concrete column with steel anchor, of steel reinforced concrete beam and column and of steel reinforced concrete beam and angle-steel concrete column with steel anchor. The parameters analysis for joint of the third type is carried on. It is indicated that the core concrete of joint is confined by the angle steel, and the shear behavior of joint can be enhanced. Meanwhile, the design formula of shear behavior for joint of steel reinforced concrete beam and angle-steel concrete column is given.
