【摘要】 TJ型屈曲约束支撑在受拉和受压两种状态下都能够达到屈服,具有良好的滞回性能,是一种良好的抗侧力构件和耗能减震构件。结合工程实例,分析了屈曲约束支撑在加固工程中的设计、施工和验收等方面的关键技术,阐述了屈曲约束支撑在加固工程中应用的显著优势。更多还原

【Abstract】 The buckling restrained brace(BRB) could yield both in tension and compression.With a good hysteretic behavior,the BRB is a kind of element which could serve as both lateral force resisting and energy dissipating component.With the introduction of several projects,the main technologies were studied such as design,construction and acceptance criteria of the application of BRB in strengthening project,and the advantage of applying this technology in the related projects was also elaborated.更多还原
