| 摘 要： | 本文研究了极限后负刚度段对钢筋混凝土框架结构地震倒塌反应的影响,从理论上探讨了结构地震倒塌模式,提出了以退化刚度比作为破坏参数的地震破坏模型,最后,通过实例数值模拟分析,重点讨论了负刚度模型对强震下钢筋混凝土框架结构的强度、变形和延性等方面特性的影响。

| Abstract: | In this paper, the influence of post-ultimate negative stiffness stage on earthquake collapase response of reinforced concrete frame structures to a severe earthquake is studied. The earthquake collapse mechanism of structure is discussed, and an earthquake damage model is proposed, with the degradation stiffness ratio as a damage parameter. Finally, the influences of the negative stiffness model on the behaviors such as strength, deformation and ductility of reinforced concrete frame structures under a strong earthquake are discussed through numerical simulation analysis of some examples. |
