摘要

为了研究新型转换层结构——预应力混凝土拱式转换层结构的薄弱部位、抗震性能及其破坏机制,对一榀预应力混凝土拱式转换层结构模型进行了静力弹塑性分析。研究结果表明:拱式转换层本身在水平荷载作用下整体性能很好,不易发生层间变形;转换层结构的底层柱以及与转换层相邻上层柱的底端是结构的薄弱环节,容易产生塑性铰,需重点加强。
For the propose of investigating the weak location,seismic performance and failure mechanisms of prestressed concrete arch transfer storey structure,which is a new type of transfer storey structure,a prestressed concrete arch transfer storey structure model was studied experimentally by pushover method.The results show that the overall performance of the arch transfer storey itself under horizontal loads is very good.It is not easy to cause interlayer deformation.The columns of the ground floor and the bottom location of the upper columns adjacent the transfer storey are the weak links of the structure.It is easy to form the plastic hinge and attention should be paid to their strengthening.
