| 摘 要： | 针对防屈曲支撑钢框架结构,建立了合理的弹塑性分析模型,选取了抗侧刚度比这一能够同时反映防屈曲支撑和框架结构特性的参量,分别对处于弹性状态及进入弹塑性状态的防屈曲支撑钢框架结构,进行了非线性时程分析并计算了结构的各项能量响应,同时还系统研究了抗侧刚度比对其能量输入和能量分配及地震响应的影响规律,并分析了抗侧刚度比的合理取值.

| Abstract: | An elastic-plastic model of buckling-restrained braced steel frame has been reasonably established.Lateral stiffness ratio can stand for the characters both of BRB and steel frame.According to the nonlinear time-history analysis and the calculation of energy response,the influence of lateral stiffness ratio to BRB steel frame has been studied including both of elastic and inelastic status.Reasonable value of lateral stiffness ratio has also been analyzed. |
