某超高层结构的扭转分析与设计
|
摘要
通过对扭转的近似计算得出减小结构扭转、增强结构抗扭能力的设计概念,将其运用到实际工程中,整体调整结构布置,对扭转位移较大的构件采用延性较好的钢管混凝土柱,使结构在地震作用下具有良好的安全储备,并进行结构安全性能目标评价和模型验证试验。
This thesis explains the design concept of how to reduce structure torsion and strengthen the structure torsion capability through approximate calculation of torsion,and apply it to real projects. By adjusting the whole structural arrangement and applying concrete filled steel tube column with better extension to object with bigger displacement,a new structure will be created and better safety reserve can be obtained even under earthquake circumstances. This new structure can give reasonable evaluation and authetication to structure safety by use of Seismic performance evaluation and model test.
