摘要
方管柱和H型钢梁采用隔板贯通式连接而成的钢框架成为多高层建筑的结构体系的一种良好的选择,在我国还没有设计准则可循。为了促进方管柱-H型钢梁隔板贯通式节点的应用,在试验数据的基础上对其进行了有限元数值分析,对比隔板贯通节点与柱贯通节点的异同点,并分析了隔板挑出长度和轴压比对节点承载力的影响,提出改进方向。
In multi-storied and high-rise buildings, there are several types to connect H-section steel beams to square tubular columns. The connection with through diaphragms is one of them, which has lower fabrication cost and convenient construction. To promote the application of H-section beam to square tubular column connection with through diaphragms, finite element numerical analysis is carried out on the basis of experimental datas. The similarities and differences are analysed between joint with through diaphragms and through columns. It also finds out the influence of diaphragm extend length and axial compression ratio on joint behavior and points out the direction of improvement.
