高β值的多层屈曲约束支撑钢框架结构设计层剪力分布研究
为了研究多层屈曲约束支撑钢框架(Buckling Restrained Braced Frame,简称BRBF)在屈曲约束支撑(Buckling Restrained Brace,简称BRB)分担率β值较高时,层剪力的优化分布,对β值约为0.9的框架振动模型(MF)和质点系振动模型(MS-0、MS-1和MS-2)进行弹塑性时程分析,研究其层剪力、层间位移角、最大倾覆弯矩及支撑固定柱的地震响应。研究结果如下:β值较高时,MF层响应值,中低楼层与质点系振动模型吻合较好,上部楼层接近质点系振动模型MS-1和MS-2。采用静力推倒法进行抗震设计时,修正底部剪力法的F1i和F2i模型分析结果与实际情况更...
