摘要对型钢混凝土梁柱节点的受力机理和影响因素进行了分析研究.根据已有的节点试验资料,对YB规程、JGJ规程、我国梁柱节点专题组建议公式、AISC规范以及AIJ规范关于节点抗剪承载力计算公式进行分析比较,结果表明:JB规程直接考虑了轴力的有利作用,计算值与试验值整体吻合较好,但对于轴压比较大的试件以及高强混凝土试件,还需要进一步修正;我国梁柱节点专题组建议公式未对型钢混凝土柱-钢梁节点以及型钢混凝土柱-型钢混凝土梁节点做深入研究,应通过更多的试验数据对其进行修正完善. Mechanical principle and impact factors of the beam-column joint of steel reinforced concrete （SRC） were analyzed. According to the test data about joint, by comparing the calculation formula of joint shear-carrying capacity provided by YB, JGJ regulation, recommended formula from China＇s Beam-Column Joint Theme Group and AISC and AIJ standards and norms, it was found that the beneficial axis effects were directly considered in JB regulation, and the whole good agreement with the experimental data was attained. But further amendment are still needed for those samples with more axis pressure and high-strength concrete specimens. What＇s more, steel beam- SRC column joint and SRC beam- SRC column joint are not deeply studied in the recommended formula of China＇s Beam-Column Joint Theme Group. Hence, it should be modified and perfected through more test data.
