Abstract:Calculating formula of mid-span deformation of concrete continuous beams strengthened with GFRP bars that considering moment redistribution is deduced. Six concrete continuous beams strengthened with GFRP bars are tested to verify the effectiveness of the formula. Reference to further research on the flexural behavior of concrete continuous beams strengthened with GFRP bars are presented.
Keywords:GFRP bars； continuous beam； moment redistribution； mid-span deformation
