摘　　要：根据国内外比较成熟的匀质弹性材料计算方法,在考虑CFRP-PCPs复合筋等效原理的基础上,对我国现行《混凝土结构设计规范》中适用于受弯构件开裂弯矩计算公式进行修正,提出了适合CFRP-PCPs复合筋混凝土连续梁开裂截面弯矩的建议计算公式.用5根连续梁的试验研究进行验证,中支座试验值与计算值之比的均值为1.02,跨中试验值与计算值之比的均值为0.99,试验结果显示吻合较好.According to the domestic and foreign mature calculation method of homogeneous elastic material and the CFRP-PCPs composite reinforced equivalence principle, we modify the formula applicable to flexural cracking moment calculation in China current 'design code of concrete structures' and put forward the crack bending moment suggested formula of CFRP-PCPs composite reinforced concrete continuous beam. The experimental study of 5 continuous beams is carried out, the ratio mean value of the middle bearing test value and the calculated value is 1.02. The ratio mean of the value midspan test value and the calculated value is 0.99. Comparisons show that the calculated values agree well with the experimental results.
