摘要
某工业研发大楼为具有两个连接体的双塔连体建筑,属于特别不规则的高层建筑结构。通过振型分解反应谱法、动力弹性时程分析以及在罕遇地震作用下的静力弹塑性Pushover分析,对该工程的结构抗震性能进行评估,考察塑性铰的发展机制,并针对薄弱部位采取相应的加强措施。
An industrial building in Shanghai is a special irregular high-rise building with two connected twin-tower structures. In order to evaluate the structural seismic behavior, the response spectrum analysis, elastic time-history analysis and static elastoplastic Pushover analysis are carried out for the connected structures. The development of plastic hinge is discussed and the weak areas are found. Strengthening mearures for those areas are presented and the conclusions can be reference for similar projects.
