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。
Using SAP2000, two three-dimensional finite element analysis models of biaxial symmetry and uniaxial symmetrical large-chassis twin-tower high-rise buildings are set up. The giant viscous damping bracing across the layers is set up to control the seismic response of structures. The vibration responses of the biaxially symmetrical and uniaxially symmetrical large-chassis twin-tower high-rise buildings and their shock-absorbing structures are analyzed by using the mode decomposition decomposition response spectrum method. The seismic response of the structure and the tower with different connections is analyzed. The seismic responses of biaxial symmetric and uniaxial symmetric double-column Siamese-dissipated structures under different seismic inputs are analyzed.
