摘要:
按我国现行抗震规范设计了12个不同层数和不同跨度的Y形偏心支撑钢框架算例,利用基于IDA
(incremental dynamic analysis)分析的能力谱方法确定了各算例的地震反应折减系数R 和超强系数Ω,分析
了结构总层数和楼层高跨比对各系数的影响.研究结果表明Y形偏心支撑钢框架的设计地震作用可在我国
现行抗震规范的基础上降低20%左右.
Abstract:
Twelve Y-eccentric braced steel frames with various stories and spans lengths were designed complying with the
Chinese Seismic Code.The response modification factors R and overstrength factors of each building were evaluated by
capacity spectrum method based on the global capacity envelops obtained from incremental dynamic analysis.Based on the
analysis results,the effects of storey numbers and spans of frames on these factors were analyzed.The results show that
the elastic design earthquake action of Y-eccentric braced steel frames can be reduced by approximately 20%on the basis
of Chinese Seismic Code.
