摘　　要：推导了考虑弯矩重分布后的GFRP筋混凝土连续梁跨中挠度的计算公式,通过6根GFRP筋混凝土连续梁试验验证了公式的适用性,为进一步研究GFRP筋混凝土连续梁的受弯性能提供了参考。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.
