[摘要] 防屈曲耗能支撐與其他類型阻尼器相比較，其顯著的特點(diǎn)是能夠提供比較大的剛度，同時(shí)在屈服后又能提供比較大的耗能，是目前效率高和普遍應(yīng)用的消能減震技術(shù)。以一個(gè)混凝土框架結(jié)構(gòu)為算例，采用Pushover分析方法，初步研究了防屈曲支撐的參數(shù)如何選取，一方面有利于提高結(jié)構(gòu)性能，另一方面能使得支撐的產(chǎn)品性能更可靠，同時(shí)使得整體結(jié)構(gòu)體系更經(jīng)濟(jì)。

Abstract: As the technique of high efficiency and wide application in energy absorption and seismic resistance, buckling restrained bracing( BRB) can provide greater stiffness and energy absorption capacity after yielding. Through Pushover analyses of a concrete frame with BRBs, the paper studied how to select parameters of BRB. The findings can be applied to improve seisrmc-resistant performance of structures. Moreover, the advantage of the findings can further guarantee the performance of BRBs and the economy of the structures.
Keywords: buckling restrained brace; performance parameters selection
