摘　　要：为验证BFRP筋在桥梁承重构件中的应用情况,对13m全长的BFRP筋和常规钢筋T型梁的抗弯载荷进行了测试。记录并分析两种筋材的试验数据,发现BFRP筋T梁的开裂荷载小于普通钢筋T梁,挠度大于普通钢筋T梁;BFRP筋T梁的裂缝比普通钢筋T梁出现得更早且后期发展较快,裂缝更宽。In order to verify the application of BFRP reinforcement in the load-bearing components of the bridge,the bending load of 13m-long BFRP reinforcement and conventional reinforced T-beams are tested.The experimental data of two types of reinforcement materials are recorded and analyzed,and it is found that the cracking load of the BFRP reinforced T-beam is lower than that of the ordinary reinforced T-beam,and the deflection is greater than that of the ordinary reinforced T-beam.The cracks in the BFRP reinforced T-beam appear earlier and develop faster in the later stage compared to those of the ordinary reinforced T-beam,and the cracks are wider.
