摘    要:首先推导了GFRP筋混凝土矩形截面梁正截面极限弯矩的计算公式,然后通过定义弯矩重分布系数分析两跨GFRP筋混凝土连续梁的极限弯矩和破坏截面,最后通过6根GFRP筋混凝土连续梁试验检验了理论分析的合理性,为GFRP筋混凝土连续梁的工程应用提供参考.

关 键 词:GFRP筋  连续梁  弯矩重分布  极限弯矩  破坏截面

Abstract:Firstly,the calculating formula of ultimate bending moment in the normal section of concrete rectangular section beam reinforced by GFRP rebars was deduced.Secondly,the ultimate bending moment and breaking section of two-span concrete continuous beam reinforced by GFRP rebars were analyzed by defining the coefficient of moment redistribution.Finally,6 concrete continuous beams reinforced by GFRP rebars were tested to verify the rationality of the theoretical analysis,which would provide references for the engineering application of concrete continuous beams reinforced by GFRP rebars.
Keywords:GFRP rebars  continuous beam  moment redistribution  ultimate bending moment  breaking section
