| 摘 要： | 首先，提出约束屈曲支撑-框架结构（BRBF）的设计流程。其次，通过罕遏地震作用下的弹塑性时程分析，得到框架损伤量沿层分布规律。基于此规律和最大名义刚度比，可以确定结构各层应布置的约束屈曲支撑内核的截面面积。最后，对此约束屈曲支撑-框架结构进行非线性动力时程分析。分析结果表明：基于框架损伤量沿层分布规律的约束屈曲支撑分布模式，在强震作用下最大层间位移角分布比较均匀，减震效果良好。

| Abstract: | Firstly ,it was proposed the design process of the buckling-restrained braces-frame structure(BRBF). Secondly ,the distribution law of the damage along the framework was obtained through the elastic-plastic analysis under rare earthquake.Based onthis distributionlawand the maxi mumnominal rigidity ratio ,it was determined the core area of the buckling-restrained braces of each storey.Lastly ,it was analyzed this buckling-restrained braces-frame structure by the method of non-linear dynamic ti me-history ana... |
