| 摘 要： | 通过对铁路站台有柱雨棚"Y"形钢筋混凝土结构典型单元的抗震全过程分析,证明其按《建筑抗震设计规范》"两阶段设计"难以满足"三性能水准"的设防目标,调整结构侧向刚度来实现满足抗震性能化设计的"两阶段设计"。既便于结构设计,又能保证结构在中震下的可修复性和罕遇地震作用下的安全性。

| Abstract: | Through the seismic analysis of a typical column "Y"shaped reinforced concrete structure unit,it is proved that the "two stage design"following Specifications for Structure Seismic Design can hardly meet the "three performance level"goal,and adjusting the lateral stiffness of the structure can meet seismic performance-based design of "two stage design ",which is advantageous for structure design,and can guarantee the reparability of the structure under medium earthquake and safety under severe earthquake. |
