[摘要] 将屈曲约束支撑用于结构体系，增强了整体结构的抗侧刚度和抗剪强度，有利于减小结构的层间位移和总体位移。将支撑应用到框架中后，结构的滞回曲线较传统的框架形状更加饱满，说明结构耗能能力得到了大幅度提高。支撑框架的骨架线的下降段也不像普通框架那样随着位移的增加加速下降，而是有下降减缓的趋势。本文试图通过试验数据说明可以考虑用支撑代替混凝土剪力墙应用于混凝土结构体系中。

Abstract: When buckling-restrained brace(BRB) is applied into structure system, it can strengthen lateral stiffness and shear strength of the structure, thus cut down the layer displacement and overall displacement of the structure. After brace is applied into the frame structure, its hysteretic curve has an essential change comparing with the traditional structure. For the influence of brace, the shape is full of energy. Furthermore, the capacity of energy consumption is improved to a large degree. The declined part of skeleton line of brace structure will not decline dramatically due to the increase of displacement like the common structure. Instead, the pace of decline slows down. The data show that it can be considered in design to adopt brace instead of shear wall in concrete structure system.

Keywords: buckling-restrained brace; reinforced concrete frame structure; experimental study
