摘要

对狗骨式刚性连接钢框架在地震作用下的响应进行分析,得到不同层数、跨数钢框架的结构延性折减系数Rμ、结构超强系数RΩ和结构影响系数R。结果表明,采用狗骨式节点刚性连接的钢框架与采用普通节点的相比,延性折减系数加大,而超强系数则减小,结构影响系数却相差不大,说明狗骨式节点的应用并不会影响钢框架的结构影响系数。
Based on elastic-plastic time-history earthquake analysis of dog-bone connection steel frame,the paper obtained the ductility reduction factor Rμ,the structural overstrength factor RΩ and the structural influencing coefficient R of dog-bone connection steel frame of different stories and spans.It is found that comparatively the ductility reduction factor of dog-bone connection steel frame is larger than that of the common joint connection steel frame,the structural overstrength factor of the former is smaller than that of the latter,and the difference of the structural influencing coefficient between them is slight,which illustrates that the application of dog-bone connection to steel frame does not influence the structural influencing coefficient R of the steel structure.
