(同济大学建筑设计研究院,上海 200092)[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。[关键词]隔板贯通式节点;滞回性能;有限元分析;方管柱;H型钢梁Seismic Performance of H-Beam to Square Tubular Column Connections with Through DiaphragmsZhuang Lei(Architectural Design & Research Institute of Tongji University,Shanghai 200092,China)Abstract: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.Keywords:joint with through diaphragms; hysteretic performance; analysis; square tubular columns; H-section beams参考文献[1]蔡益燕. 阪神地震后日本钢结构的发展[J]. 中国建筑金属结构,2005,(8).[2]日本建筑学会. 钢结构接合部设计指针(Recommendation for design of connection in steel structures,原文为日文)[S],2001.[3]日本建筑中心. 冷成型方钢管设计施工手册(冷间成形角形钢管设计施工マニユアル,原文为日文)[S],2003.[4]刘洋.冷弯方管柱与H型钢梁连接性能的分析[D].武汉:武汉理工大学.[5]石井匠,菊川春三,森田耕次,等. 通しダィアフレム形式柱梁接合部の破断性状に关する试验的研究[C]. 钢构造论文集,1999,6(24):87102.[6]李星荣,魏才昂,等. 钢结构连接节点设计手册(第二版)[M]. 北京:中国建筑工业出版社,2005.
