Abstract
In order to study the ultimate flexural capacity of reinforced concrete beams with BFRP (Basalt fiber reinforced polymer), the test is designed and poured four T-section reinforced concrete beams. At first, monotonous static loading is carried on two of the beams until the chinks appeared. Afterward, all beams are strengthened by BFRP sheets. The contrast experiment studied and analyzed the different cracking load, ultimate load, deflection, reinforcement strain, concrete strain, fiber cloth strain, crack development of pre-reinforced beams and damaged beams strengthened by BFRP sheets. At the same time, the theoretical analysis and finite element simulation are performed to verify the result of experiment. The results show that the ultimate flexural capacity of reinforced concrete beams with BFRP has significantly increased. The circular bead treatment raises woke effect and reduces stress concentration of BFRP sheets.
