[摘要] 以河北省图书馆加固改造为例，介绍了采用防屈曲支撑消能减震的设计过程。结合2根支撑构件试验结果及相关规范，验证本工程所用支撑具有良好的滞回性能。经软件计算，对比支撑设置前后整体结构的动力特性、强度和层间位移的变化，分析工程消能减震设计的效果，验证设计的合理性。

Abstract: Based on Hebei Library reinforcement engineering, the energy-dissipated design process of buckling-restrained brace( BRB)  was introduced. The well hysteretic characteristics of two braces are certified by test. The calculated results of the integral stmcture are contrasted, such as dynamic behavior, intensity and story displacement. The results show that the design is rational.
Keywords: buckling-restrained brace; energy-dissipated; hysteretic characteristics; dynanuc behavior
