【摘要】 大底盘双塔结构是指将底部几层公共空间设置为大底盘,在楼层上部用两个塔楼作为主体的结构,而在塔楼间的某些楼层用连体连接起来,就成为了大底盘双塔楼连体高层建筑结构。在近些年,此类结构在国内外的各种工程中均有应用。运用ANSYS有限元程序采用振型分解反应谱法对大底盘双塔连体结构进行分析,得到不同的抗震性能结果。更多还原

【Abstract】 The twin-tower connected structure with an enlarged base is a structure widely applied in practical engineering in recent years.It is compose of an enlarged base and two symmetrical towers,with connective structures overhead joining the twin towers together.The current thesis is set to study the dynamic characteristics and seismic response of the structure and how the analytical results vary with different arrangement plans:number and position of the connections.In recent years,this type of structures are widely used in engineering in China and aboard.By analyzing the twin-tower with different connective structure using different seismic response resulting from using different arrangements of connections,an optimal arrangement plan is recommended afterwards.更多还原
