大型球体建筑的扭转效应控制

Control of Torsion Effect of Large Ball Building

一般建筑的抗震扭转效应控制是通过在建筑的合适部位设置一定数量的剪力墙得以实现,但是对于大型球体建筑,如何控制其扭转效应,尚无一定的设计经验。文章以杭州国会中心项目为例,详细探讨径向斜撑与环向斜撑对建筑物地震扭转效应控制所起的不同作用,对今后类似球体建筑的结构设计具有借鉴意义。

Control of anti-seismic torsion effect of general buildings is realized by setting up a certain number of shear walls in appropriate positions of building, however, for large ball building, how to control its torsion effect, there is no experience in design. Taking Hangzhou International Conference Center Project for example, this article makes detailed discussion of different roles of radial brace and circumferential brace in control of anti-seismic torsion effect of building, which provides reference for structure design of similar ball buildings in future.
