摘要
通过对钢筋混凝土梁加受拉钢筋加固的受力分析,得到了钢筋混凝土梁原截面是否足够的判断式,分析了梁中原有钢筋加固前、后的应力变化并给出其计算公式,从而建立了加受拉钢筋对梁加固时正截面承载能力的计算方法,为加受拉钢筋对梁加固设计提供了理论依据。
The judgment formula for section of reinforced concrete beam whether being sufficient was got by analyzing concrete beam＇s force strengthened with tensile steel, and what was analyzed that the stress change of existing steel pre-and post beam being strengthened, then its calculation formulas were given. Thus the calculation method of concrete beam strengthened with tensile steel was established, which supplies the theory basis for concrete beam strengthened by tensile steel.
