摘　　要：隅撑支撑框架(KBF)是一种新型的耗能支撑结构体系,本文主要研究了它的弹塑性分析模型。首先提出了隅撑支撑钢框架的恢复力模型;其次,提出了隅撑支撑耗能体系的分析模型,并给出了隅撑支撑耗能体系的等效阻尼和刚度的计算方法;然后,给出了隅撑支撑钢框架的弹塑性分析方法;最后通过算例验证了本文方法的正确性。The knee-brace-frames （KBF） is a new kind of energy dissipation bracing frames, its elastic-plastic analysis model has been discussed in the paper. First of all, Restoring force model of KBF is established. Secondly, analyzing model of knee-brace and computattional method of equivalent damping and stiffness of knee-brace are established. Thirdly, elastic-plastic analysis method of KBF is presented. Finally, an example is presented to verify the method in the paper.
