摘要
本文在本课题组和国外FRP筋混凝土梁试验结果的基础上,对我国《混凝土结构设计规范》(GB50010-2002)和《水工混凝土结构设计规范》(SL/T191-96)中纵向钢筋相对粘结特性系数、钢筋混凝土梁裂缝截面内力臂长度系数以及考虑钢筋表面形状的系数进行修正,提出FRP筋混凝土梁最大裂缝宽度设计建议。与ACI440.1R-06相比,采用本文建议公式的最大裂缝宽度计算值与试验值更为吻合。
Based on the test results, design code for concrete structures （GB50010-2002） and design code for hydraulic concrete structures （SL/T191-96） including the relative bond coefficient of REBARs, the coefficient of internal force arm of steel-reinforced concrete beams, and the factor accounting the surface of REBARs are modified. The design recommendations for the cracking width of concrete beams reinforced with FRP REBARs are presented in this paper. Finally, the comparison between the theoretical values of AC1440.1R-06 and the predicted result by using the design recommendations has been discussed.
