防屈曲支撑现状与研究进展综述

A review of the current status and research progress of anti-buckling braces

防屈曲支撑是一种兼具普通支撑和金属阻尼器双重功能的支撑形式,具有良好的滞回特性,主要由支撑内芯,外围约束构件组成,在耗能减震领域得到了广泛的应用。综述了防屈曲支撑的构造及受力原理,介绍了近年来国内的相关研究进展与成果,并总结了仍需要进一步研究的问题。

The anti-buckling support is a form of support that combines the dual functions of a common support and a metal damper.It has good hysteresis characteristics and is mainly composed of a supporting inner core and a peripheral constraining member.It has been widely used in the field of energy consumption and shock absorption.This article summarizes the structure and stress principle of anti-buckling brace,introduces the related domestic research progress and achievements in recent years,and summarizes the problems that still need further research.
