摘　　要：屈曲约束支撑在拉力和压力的作用下都能屈服而不屈曲,具有良好的滞回性能,因此应用广泛。新型屈曲约束支撑种类层出不穷,其正向着材料更加轻质高能、加工安装过程更加简便、支撑性能更加丰富优越的方向发展。通过总结屈曲约束支撑的发展趋势,介绍多种相关新型屈曲约束支撑,并对未来屈曲约束支撑的发展趋势进行展望。Buckling restrained brace may cause yield under both tension and compression without buckling,it has been widely used because of good hysteresis behavior.Many new types of BRBs are constantly emerging,the materials of BRB is becoming lighter and more high-performance,the fabrication and installation is easier and the bracing performance is richer and more superior.Through the summarization of development trend of BRB,various related new types of BRBs were introduced.The development trend of BRB in future was prospected.
