超高层建筑连体结构分析

Analysis of super high-rise connected structures

某项目为两栋超高层,在高空(分别位于13层、30层)采用连体结构,为确保连体结构超高层建筑的安全性,应准确分析连体结构对主体建筑产生的影响,以及连体结构形式的选择、连体结构与塔楼的连接方式、连接节点的做法,研究连体结构对超高层塔楼的影响范围。文章对比了连体结构与单塔结构、双塔非连体结构的塔楼振动特性,分析主要连接节点的应力情况,寻求超高层连体结构的设计可行方案。

One project is two super-high-rise buildings with connected structure at high level(located at 13th and 30th floor respectively).In order to ensure the safety of connected structure on super-high-rise buildings,it analyzes the influence of connected structure on the main building,the selection of connected structure form,the connection mode between connected structure and tower,and the method of connecting nodes.It studies the influence of connected structure on super-high-rise buildings and the influence scope of connected structure on tower.In this paper,the vibration characteristics of towers with connected structure are compared with those with single tower structure and double towers without connected structure,and the stress of main connection nodes is analyzed to seek a feasible design scheme of connected structure.
