摘要
屈曲约束支撑是在普通钢支撑基础上改进而成的一种受压、受拉都能屈服而不屈曲,利用软钢屈服耗能能力好、承载能力高的一类金属屈服型阻尼器。论文对屈曲约束支撑的基本构造、工作机理、主要特点、设计依据、结构设计、布置及连接、工程应用等进行了概述和讨论,为屈曲约束支撑的设计和应用提供参考。
Buckling-restrained brace is one kind of metal yield energy dissipating device based on conventional steel brace.Buckling-restrained brace has capacity of yielding subjected to compression or tension, efficient energy dissipation because of the use of low yield point steel, high carrying capacity. Main aspects of buckling-restrained brace including configuration, working principle, main characteristics, design basis, structural design, installation and maintenance, project application were summarized and discussed in this paper. Furthermore, reference for design and adoption of spherical bearings could be provided.
