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。 By analyzing the dynamic characteristics and the seismic response of two typical multi-tower structures under earthquake and comparing with the stress characteristics of the single-tower model, the floor stress analysis and temperature effect analysis of the complex connected parts of the large chassis are carried out. The dynamic characteristics of multi-tower structure under different conditions, the shear-stress transfer law between the tower and the podium and the influence on the floor stress distribution are obtained, and some effective seismic strengthening measures are taken.
