| 摘 要： | 提出用热轧角制作钢防屈曲支撑,简称BRAB.设计制作了2种组合截面,即等肢双角钢错十字截面和不等肢双角钢T字截面,共4个防屈曲支撑试件.为检验其构造合理性及抗震性能,进行了低周反复荷载加载试验.对试件的力一位移滞回曲线、割线刚度及其退化规律、等效黏滞阻尼比等抗震性能进行了研究.结果表明,所研制的这种组合热轧角钢防屈曲支撑构造合理、工作可靠、耗能能力强、抗震性能优越.

| Abstract: | A new conformation type of buckling-restrained brace suitable to Chinese market is developed.The brace is made of hot-rolled angle steel,and called BRAB for shortly.Four specimens,including quasi-cross and T section,are designed and manufactured.Cyclically loading tests are conducted.Seismic performances, such as force-deformation loops,tangent stiffness and its deterioration,as well as equivalent damping ratio are studied.It is proved that the BRAB has a reliable conformation with high energy dissipation and excellent seismic behaviors. |
