【摘要】 通过1∶2隅撑支撑钢框架模型的单调加载试验,研究了隅撑支撑钢框架的抗侧力性能和破坏机理。试验结果表明,在水平荷载作用下隅撑最先发生屈服,并具有很好的变形能力,结构具有很好的滞回耗能性能和延性。对隅撑支撑钢框架进行了弹塑性受力分析,并给出了其恢复力模型,从而为简化隅撑支撑钢框架的非线性分析提出了一种新的方法。更多还原

【Abstract】 Experiment on 1∶2 model of the knee-braced-steel-frame was conducted under monotonic load to investigate the lateral load-resisting performance and its failure mechanisms.The experimental results show that under horizontal loads the knee element can yield firstly and has excellent deformation capacity.This makes the knee-braced-steel-frame has excellent capacity of energy dissipation and ductility.Then the knee-brace-steel-frame is elastic-plastic analyzed and its restoring force model is given to present a new way that can simplify the nonlinear analysis of the knee-braced-steel-frame.更多还原
