摘要
国内建筑业虽然还处于大规模兴建阶段,但是由于外界环境以及结构自身的原因,加固改造工程也在不断增多。工程结构是否要加固主要看工程结构是否满足预先的设计功能要求。当工程结构快要达不到或已经达不到设计的功能要求时,应当考虑进行加固改造。介绍了结构既有钢筋混凝土结构梁加固的理论研究,并依次分析了增大截面加固法、粘贴钢板加固法和粘贴碳纤维复合材加固法的设计理论。
Although the domestic construction industry is still in the stage of large-scale construction, due to the external environment and structural reasons, the reinforcement and transformation projects are also increasing. Whether the engineering structure is to be reinforced depends on whether the engineering structure meets the pre design function requirements. When the engineering structure can not reach or has not reached the functional requirements of the design, it should be considered to reinforce the transformation. Firstly, this paper introduces the theoretical research of reinforced concrete beam reinforcement. Secondly, the resistance analysis model and load statistical model of existing reinforced concrete beams are given, and the design theory of enlarging section reinforcement method, sticking steel plate reinforcement method and sticking carbon fiber composite material reinforcement method are introduced in turn.
