摘　　要：介绍了2个外包钢-混凝土组合梁与钢管混凝土柱的连接节点,并对其进行了低周反复荷载作用下的试验研究。对节点的破坏形态、滞回曲线、强度、延性和钢筋、钢板的应变等性能进行了分析。结果表明,通过合理的构造措施,外包钢-混凝土组合梁与钢管混凝土柱的连接节点具有较强的受剪承载力、较好的延性和耗能能力,能够满足工程要求。并在此基础上对节点的受力机理进行了探讨,提出了节点核心区受剪承载力的计算公式,计算结果偏于安全。The paper introduced two joints joining the outer-plated steel-concrete composite beam and concrete filled steel tube column,for which the low-cycle repeated load tests were conducted.The paper also analyzed the joint performances such as the failure modes,hysteretic curves,strength,ductility,and strains of the steel bars and the steel plates.The joints show the significant shear-resistant capacity,better ductility and energy dissipa-tion ability by the appropriate constructional measure so as to greatly satisfy the engineering requirement.Based on the analysis,the force mechanism of the joint is investigated,and the formula for calculating the shear capaci-ty in the central area of the joint is presented,the calculated results are smaller than that of the test.
