摘要

运用SAP2000建立了双轴对称和单轴对称的大底盘双塔连体高层建筑两个三维有限元分析模型,在连体中设置跨层的巨型黏滞阻尼斜撑来进行结构的地震响应控制,运用振型分解反应谱法对双轴对称和单轴对称大底盘双塔连体高层建筑及其减震结构的地震响应进行了分析,分析了连体与塔楼采用不同的连接方式对结构减震效果的影响,并分析了不同地震输入下双轴对称和单轴对称双塔连体耗能减震结构的地震响应。
Two-tower-connected high-rise building with enlarged base is a kind of complex structure system,seismic energy dissipation technology is introduced to control the structure's response.Based on 3-D finite element analysis by SAP2000,two models of biaxial axial symmetric and single axial symmetric two-tower-connected high-rise buildings with enlarged base were constructed respectively.Seismic response analysis of biaxial axial symmetric and single axial symmetric two-tower-connected high-rise buildings with enlarged base and corresponding seismic mitigation structures were proceeded by vibration model response spectrum method,the influence of different connecting methods on the structure in seismic resistance was investigated.
