钢框架与偏心支撑结构性能对比分析
首发时间:2010-01-07
摘要:在已完成设计的钢框架上布置支撑,然后利用通用有限元分析SAP2000,对其进行模态分析、反映谱分析、弹型、弹塑性时程分析,从中得到布置上支撑后结构的自振周期,刚度,强度等性能的变化情况,通过对比分析可以看到,支撑的布置对钢框架结构性能有明显的提高。

Comparative Analysis of Performance in Steel Frame and Eccentrically Braced Steel Frames
Abstract:In this paper the designed steel frames are analyzed with the SAP2000 after the braces arranged,the analysis contains modal analysis, response spectrum Analysis, elastic and elastic-plastic time history analysis.there are many changes on natural period of vibration, stiffness, strength of the steel frames after the braces arranged.The performance of the steel frames are greatly enhanced when the braces are arranged by Contrastive analysis.
Keywords: steel frames braces modal analysis response spectrum Analysis time history analysis
