依据平截面假设，对外粘钢板加强钢筋混凝土梁正截面强度进行分析，其中包括梁在卸载后粘钢板，再重复加载至破坏的整个变形过程分析；外粘钢板面积对梁弯曲承载力的影响；原始配筋率对梁承载力提高幅度的影响；混凝土强度等级以及钢筋级别的影响。通过四根梁的实验，验证了理论分析结果。
According to the assumption of plane section, the strength of the reinforced concrete beam reinforced by external bonded steel plate is analyzed, including the analysis of the entire deformation process after the beam is unloaded and the steel plate is repeatedly loaded to failure; the influence of the area of the bonded steel plate on the bending capacity of the beam is analyzed. The influence of the original reinforcement ratio on the increase of the bearing capacity of the beam; the influence of the concrete strength level and the reinforcement level. Through the experiment of four beams, the theoretical analysis results were verified.
