将屈曲约束支撑应用于带加强层的高层建筑结构中,分析了结构在大震作用下的弹塑性响应及构件破坏模式,得出了如下结论:在高层建筑加强层中采用屈曲约束支撑作为其斜腹杆构件,有利于防止加强层斜腹杆受压屈曲破坏并保障核心筒与外框架的协同工作,是实现有限刚度加强层与延性破坏机制的一种有效途径。
The buckling restraint brace is applied to the high-rise building with stiffener. The elastoplastic response and the failure mode of the member under the action of large earthquake are analyzed. The following conclusions are drawn: buckling restraint brace is adopted as the stiffener in high-rise building Oblique web members are conducive to prevent buckling of the slant web under buckling and ensure the cooperation between the core tube and the outer frame. It is an effective way to realize the mechanism of ductile failure and ductile failure of finite stiffness.
