摘要
由于塔楼高度较高,为加强结构整体抗震性能,提高核心筒整体延性,取底部核心筒墙肢为关键构件,确保其中震作用下墙肢抗弯不屈服、抗剪弹性、大震作用下墙肢受剪截面满足规范要求。通过大震动力弹塑性分析研究核心筒整体损坏情况,验证其具有较好的延性。
As the height of the tower exceeds the height limit,in order to enhance the overall seismic performance of the structure and improve the overall ductility of the core wall,the bottom core wall is designated as key component.Equivalent linearization method was used to investigate that the cross section do not yield and diagnal section keep elastic under moderate earthquake,and the section meets the minmum shear demand under major earthquake.Through the elasto-plastic dynamic analysis udner major earthquake,the overall damage of the core wall was studied and results shows that good ductility was acquired.
