钢管混凝土柱节点受力性能及设计方法研究

Study on the behavior and design method of concrete-filled steel tubular joints

通过对钢管混凝土柱节点竖向承载力试验、三维有限元分析和低周反复荷载试验,分析了结构的受力特征、破坏机理、抗震性能,对其设计方法进行了研究,并提出了设计建议。

Through the vertical bearing capacity test,low-cyclic reverse loading test and three dimension finite element analysis on concrete-filled steel tubular,the behavior and failure mechanism and seismic behavior of joints are analyzed in this paper,the design of joints is studied,and design suggestion are proposed finally.
