屈曲约束支撑在高层建筑结构加强层中的工程应用
Application of buckling restrained braces in a high-rise structure with strengthened story
【摘要】 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。
【Abstract】 With application of buckling restrained braces in a high-rise structure with strengthened story,the elastic-plastic responses and damage modes of the structure under rare earthquake were summarized.Some beneficial conclusions were proposed: buckling restrained brace used as the diagonal brace members in strengthened story of high-rise structurs can prevent buckling failure due to compression and ensure the collaborative work between core wall and frame;it is also on effective way to limit the stiffness of strengthened story and realize the ductile failure mechanism.
