摘要
防屈曲耗能支撑作为一种具有应用前景的耗能减震构件,克服了传统支撑受压屈曲的缺点,地震时具有良好的耗能能力和延性。本文阐述了防屈曲耗能支撑的原理,介绍了其类型、性能以及应用防屈曲耗能支撑进行抗震加固的设计方法,给出了防屈曲耗能支撑在结构加固中应用的典型实例,提出了防屈曲耗能支撑应用于加固工程领域中需加强研究的一些问题。
As a kind of prospective energy dissipation and vibration reduction component,buckling-restrained brace(BRB) overcomes the buckling characteristics of conventional braces,and it behaves nice energy dissipation capacity and ductility when subjected to the earthquake.In this paper,the mechanism of BRBs is presented,and the types,performance and design methods are introduced.In addition,some applications in the seismic rehabilitation are enumerated and some problems to be solved in the future are proposed.
