摘　　要：抑制屈曲支撑体系是一种机敏的减震支撑体系,介绍了抑制屈曲支撑研究的发展和基本概念,进行了抑制屈曲支撑的整体稳定研究,推导了有初弯曲的抑制屈曲支撑的临界荷载和挠曲方程,以及在内核上的分布荷载的β参数和与β参数相关的参数。Buckling restrained brace system is a smart support system of damage reduction. The development and the behavior of buckling restrained brace are introduced. Through the global stability (analysis), the critical load and deflection equation of buckling restrained brace with initial deflection is obtained. The parameter β in relation to the distribution load acting on the inner core and the parameters in relation to β are presented.

关 键 词：抑制屈曲支撑 整体稳定 临界荷载 侧撑构件 内核
