| 摘 要： | 介绍了2个外包钢-混凝土组合梁与型钢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.试验结果表明:通过合理的构造措施,外包钢-混凝土组合梁与型钢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.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,计算结果和试验结果吻合良好. |

| Abstract: | The low-cycle repeated load tests were conducted for two joints connecting the outer-plated steel-concrete composite beam and reinforced concrete column,and the performance of the joints such as the failure modes,hysteretic curves,strength,ductility,and strains of the steel bars and the steel plates is analyzed.The result of the experiment indicates that significant shear-resistant capacity and satisfactory energy dissipation ability can be obtained by appropriate constructional measure so as to satisfy the engineering requirement.Based on the analysis of test data,the force mechanism of joint is investigated and the formula for calculating the shear capacity of the joint is presented,the calculated results agree well with that of the test. |
| Keywords: | outer-plated steel-concrete composite beam shaped-steel concrete column joint shear-resistant capacity ductility energy dissipation ability |
