| 摘 要： | 采用结构的变形破坏准则，以基于不同抗震功能要求的结构最薄弱层间变形可靠指标作为参照指标，对钢筋混凝土框架结构发生局部破坏后的抗震可靠度进行了分析，并对不同的局部破坏模式进行了对比研究，以期找出对结构最不利的局部破坏模式，以及结构可以接受的局部破坏模式，从而为结构的抗震设计提供一些借鉴，另外，还提出了结构可靠度分析的近似简化方法。

| Abstract: | The reliability analysis of RC frames with partial damage under earthquake action is studied using the damage criterion of structural deformation according to performance based structural story deformation reliability index of the weakest story considering different seismic requirements. The different partly damaged modes with different stiffness degradation ratio of RC frames are studied and compared in order to find out the dangerous and acceptable partly damaged modes, which may give some useful suggestions to structural seismic design. The simplified approximate approach to structural reliability analysis is also introduced. |
