针对上海世博会保留原有工业建筑的改建项目,从材料的应力-应变关系的层次上,将原烟囱结构模拟为环形剪力墙结构,对改建烟囱进行了罕遇地震下的弹塑性时程分析,同时对该工程的结构抗震性能进行评估。
In view of the reconstruction project of the original industrial building in Shanghai World Expo, the original chimney structure was modeled as a ring-shaped shear wall structure at the level of the stress-strain relationship of materials. The elastoplastic time-history analysis of the chimney under rare earthquakes was carried out , At the same time to evaluate the seismic performance of the project.
