摘要
通过对两种典型的多塔结构在地震作用下的动力特性、地震响应进行分析,并和单塔模型的受力特性进行对比,同时对大底盘复杂连接部位进行楼板应力分析和温度效应分析,得出了不同情况下多塔结构的动力特性、塔楼与裙房地震剪力传递规律及对楼板应力分布的影响,并采取了一些有效的抗震构造加强措施。
Dynamic characteristics and seismic response under the seismic actions of two typical multi-tower structures were analyzed and compared with mechanical characteristics of the single-tower model. Meanwhile,slab stress analysis and temperature effect analysis of complex connection parts of the enlarged base were carried out. The dynamic characteristics of multi-tower structures,the seismic shear force transmission law between tower and podium,and the influence on floor stress distribution under different conditions were obtained. And some effective seismic structural measures were proposed to strengthen the structure.
