充分利用既有建筑,在保证安全的同时增加新的使用功能,建筑结构加固发挥着越来越重要的作用。本文针对混凝土结构的加固特点,结合工程实例,着重分析研究既有柱的加固方法,新增梁柱节点的锚固技术及受力问题,以期寻求一种较为可靠、经济、合理的加固方式。 Making full use of existing buildings, adding new functions while ensuring safety, strengthening of building structures plays an increasingly important role. In this paper, according to the reinforcement characteristics of concrete structures, combined with engineering examples, the emphasis is put on the reinforcement methods of existing columns, the anchoring technology of new beam-column joints and the problem of bearing capacity, so as to seek a more reliable, economical and reasonable reinforcement method.
