建造于地铁站上的超高层塔楼结构设计

Structural design of the super tall building located on the railway station

某塔楼高248.9m,存在较多斜柱,且设置有两道加强层。加强层包括伸臂桁架和环桁架,底部和顶部存在40多米高跃层柱,中部多层楼板开大洞,属于特别不规则的超限超高层建筑。场地横跨地铁站和盾构隧道,超高层塔楼紧邻地铁站及地铁盾构隧道。介绍了结构在不同水准地震作用下,设计时所考虑的各种因素、进行的计算分析和采取的措施,希望能给类似的工程设计提供参考。

The building with 248.9m height is an irregular out-of-codes super tall building, which includes many inclined columns, two stories with outriggers and belt trusses, and some big openings in the middle floors. Columns, which pass through several floors in the bottom and the top of the building, are more than 40m. Moreover, the super tall building strides across a railway station and a shield tunnel. The design factors of analysis process and seismic measures under different seismic actions were introduced for reference.
