摘要
梁柱节点连接对钢框架抗震性能有显著影响.介绍了1994年美国北岭地震和1995年日本阪神地震后钢框架新型延性节点的研究与发展状况;说明了塑性铰外移RBS连接设计的必要性和基本形式;介绍了美国联邦突发事件管理局对RBS连接钢框架的设计方法,并阐述了对其改进的方法;提出了目前钢框架塑性铰外移新型延性节点研究尚需解决的关键科学问题.
The anti-seismic performance of steel moment resisting frame is greatly varied in different beam-column connections. A brief review on beam-column connections used in steel moment resisting frame after 1994 Northridge earthquake and 1995 Kobe earthquake is presented and the necessity of assuring sufficient deformability of steel beam end plastic hinges in moment resisting frame structures is also discussed. Details of reduced section, or so-called dog-bone are reviewed. Design methods based on the US FEMA guidelines and recent research for steel moment resisting frame structures are studied. The key problems needed further research on new type ductile connection of steel frames using idea of shifting away plastic hinge are proposed in this paper.
