上海某大底盘多塔超限高层结构分析与设计

Structural analysis and design of an out-of-code high-rise multi-tower building in Shanghai

分析某大底盘结构。本项地下2层,地上10层(包含地上2层裙房和6栋塔楼),建筑高度44m,采用钢管混凝土框架结构体系。本文提出了大底盘结构的加强措施,对楼板进行了温度影响分析,并进行大震下的弹塑性时程分析,实现“三水准”的抗震设计。

The paper mainly introduces the structural analysis of a multi-tower commercial complex in Shanghai.The towers are 44m high,with 10 floors above ground and 2 floors Underground.The analysis focuses on slab stress under temperature fluctuations and elastoplastic dynamic time history analysis.Finally,the comprehensive analysis shows that the building structure achieves the performance target of“level 3”seismic design.
