建筑物由于年久失修、遭遇灾害,其结构性能会发生变化,因此,改造前必须对其进行可靠性鉴定,依据鉴定意见进行改造加固设计。只有做到认真检测、科学评估、周密设计、精心施工,才能确保改造后建筑结构的使用安全。本文详细说明了混凝土结构改造加固的方法,并强调了设计要点。 Due to the disrepair of buildings and their disasters, the structural performance of the buildings will change. Therefore, the reliability assessment of the buildings must be carried out before the reconstruction and the reinforcement design should be carried out based on the identification opinions. Only by careful examination, scientific assessment, careful design and meticulous construction can we ensure the safe use of the building structure after the renovation. This paper describes in detail the method of rebuilding and reinforcing concrete structures, and emphasizes the design points.
