摘　　要：提出了隅撑支撑耗能体系的概念,给出了隅撑支撑钢框架的分析模型,并通过有限元分析验证了该模型的正确性,最后通过分析隅撑支撑钢框架的工作机理给出了其简化恢复力模型,从而可以使其弹塑性分析得到简化。The paper gave the conception of the knee-bracing energy-dissipation system, and then analysis model of KBF was presented. Second, the correctness of analysis model was verified by finite element analyzing. Finally, the restoring-force model of KBF was presented by analyzing the behavior mechanism of KBF. Then elastoplastic analysis could be simplified.
