摘要
采用非线性程序Perform-3D进行某超高层结构弹塑性时程分析,48层以下为框架-核心筒结构,其上为钢框架-核心筒结构,每层剪力墙筒体外墙外飘2m左右厚500mm的厚板,用扁梁将外围柱和剪力墙筒体连接。根据结构层间位移角、楼层剪力、构件耗能、钢材屈服和剪力墙损伤等计算结果,找出结构薄弱位置,分析罕遇地震下结构的抗震性能,为设计提供依据。
Perform-3D software is adopted to execute nonlinear time-history analysis for a high-rise structure,which is frame-core tube structure from 1F to 48F and is steel frame-core tube structure from above 48F. Each floor perimeter shear wall tube wall extend about2m slab with the thickness of 500mm,and flat beam connect peripheral column with shear wall tube. Based on the story drift of the structure,story shear,component energy,steel yield and damage of shear element,the weak parts is defined and seismic performance is analyzed under strong earthquake,which can be referred to the seismic design.
