摘　　要：隅撑支撑框架是一种新型的耗能支撑钢框架结构形式,在小震作用下,具有较大的抗侧移刚度,在大震作用下,具有较好的耗能性能。隅撑是隅撑支撑框架中的耗能构件,其设计参数对隅撑支撑框架的抗震性能有重大影响。本文主要通过非线性有限元分析,探讨了隅撑的设计参数对隅撑支撑钢框架抗震性能的影响。Knee-brace-frame is a new kind of energy dissipation bracing frames. Knee-brace-frame has large lateral rigidity under small earthquakes and excellent capacity of energy dissipation under strong earthquakes. Knee elements are elements dissipating energy in knee-brace-frames and their design parameters have great influence on the earthquake-resistant performance of knee-brace-frames. The paper investigates the influence of the knee element on the earthquake-resistant performance of steel knee-brace-frames by nonlinear finite element analysis.
