[摘要] 防屈曲耗能支撑与其他类型阻尼器相比较，其显著的特点是能够提供比较大的刚度，同时在屈服后又能提供比较大的耗能，是目前效率高和普遍应用的消能减震技术。以一个混凝土框架结构为算例，采用Pushover分析方法，初步研究了防屈曲支撑的参数如何选取，一方面有利于提高结构性能，另一方面能使得支撑的产品性能更可靠，同时使得整体结构体系更经济。

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
