| 摘 要： | 结构的地震破坏可看作是超过屈服后的非弹性阶段的低周疲劳问题，而单根柱的破坏分析是整个框架失效分析的基础，本文通过八根１／２比例的钢筋混凝土柱在不同位移幅值下的等幅低周疲劳试验和六根非对称位移循环下低疫疲劳试验，探讨了在不同位移幅值下降筋混凝土柱累积损伤的发展规划以及低周疲劳寿命的表达式，给出了低周疲劳寿命不同位移水平下正负位移幅值比之间关系的表达式。希望以此为基础，建立更为合理的结构抗震破坏准则。

| Abstract: | Under seismic action the damage of critical regions in ductile reinforced concrete structures can be regarded as combined results of cumulative damage caused by positive/negative displacement levels after yielding. On the basis of symmetric and non-symmetric cyclic fatigue experiments on 14 half-scale RC columns under displacement levels the development of cumulative damage and relationship between low-cyclic fatigue life and displacement amplitude are investigated. It is hoped that on this ground more rational damage criteria for RC earthquake - resistant structures can be put forward. |
