摘要
屈曲约束支撑是一种新型的耗能型结构支撑,用于结构抗震加固优势非常显著。本文通过北京市顺义区某小学南教学楼结构加固中防屈曲耗能支撑技术的应用,介绍了这种新型结构的详细施工过程(方法)。整个施工过程综合考虑了节点、外装饰立面等建筑方面的要求,并对屈曲约束支撑在结构加固施工中一些常见难点问题的解决方法进行了解析。这些施工难点问题的解决,不仅对屈曲约束支撑在结构加固中的应用将起到积极的推动作用,而且也给其他结构的施工提供可供借鉴的参考。
Buckling-restrained brace（BRB） is a new type of composite bracing members which can act as conventional brace without buckling.And there are many advantages for BRB using in structure strengthen.In this paper,the construction process of BRB used to strengthen a primary school building in Beijing is discussed.By hard work of construction,some difficult techniques of BRB are settled,and the design seismic behaviors of the building are improved largely.
