[摘要] 以河北省圖書館加固改造為例，介紹了采用防屈曲支撐消能減震的設(shè)計(jì)過(guò)程。結(jié)合2根支撐構(gòu)件試驗(yàn)結(jié)果及相關(guān)規(guī)范，驗(yàn)證本工程所用支撐具有良好的滯回性能。經(jīng)軟件計(jì)算，對(duì)比支撐設(shè)置前后整體結(jié)構(gòu)的動(dòng)力特性、強(qiáng)度和層間位移的變化，分析工程消能減震設(shè)計(jì)的效果，驗(yàn)證設(shè)計(jì)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
