不同连接体大底盘多塔高层建筑结构抗震性能分析

由于大底盘多塔连体高层建筑特有的结构形式,在外力作用下结构受力性能极其复杂。目前,学术界和工程界在理论分析和试验研究上分析较多的是对大底盘双塔连体结构的研究。而对于三塔及多于三塔的建筑结构的受力性能研究较少。论文采用有限元分析软件ETABS利用振型分解反应谱法,分析了不同连接体参数变化下的大底盘三塔连体高层建筑结构在多遇地震作用下的结构抗震性能规律。通过上述分析结果,总结结构抗震性能规律,为工程设计提供合理的建议。

Seismic Analysis of Different Multi-Tower Connecting High Building Structures with A Large Base Subjected

Due to unique structural form, the structural force performance is extremely complex under the action of external force. According to the current study status, the majority of experimental analysis and theoretical research is on the two-tower connecting building structures with a large base subjected in the academic and engineering circles. However, the multi-towers is very few. In this paper, it was analyzed that dynamic characteristics and seismic performance of structure under the action of frequent seismic by using finite element analysis software ETABS and formation decomposition response spectrum method. Through the above analysis result, the rules of the structural seismic performance were summed up. Then reasonable suggestions were provided for the engineering design.
