【摘要】 依据《混凝土结构设计规范》(GBJ10-89)和《混凝土结构加固技术规范》(CECS25:90),基于平截面假定,考虑二次受力,提出了不同卸载条件下外贴碳纤维加固钢筋混凝土梁的正截面承载力计算公式及其适用条件,理论计算与试验结果比较吻合,可供工程设计参考。更多还原

【Abstract】 According to technical specification for strengthening concrete structures and design specification for concrete structures, based on the assumption of plane section, a method for calculating the ultimate capacity of reinforced concrete beam strengthened with carbon fiber reinforced plastic(CFRP) plates is proposed considering the effect of secondary loading for different unloading conditions.The calculation results agree with the experimental results. The design method can be available for reference in design.更多还原
