Flexural Performance of BFRP Bar Reinforced High-Strength Concrete Beam
Although fiber reinforced polymer (FRP) can improve the bearing capacity of concrete structures, it always shows the brittle failure. This paper used high strength concrete RPC combined with BFRP bar to produce a new type of beam. The results of a four-point bending test shown that: the RPC-BFRP beam presented a plastic failure model as its load-deflection curve was similar to the steel bar RC beam. Otherwise, the BFRP bar reinforced normal concrete beam gave out a brittle failure as its load-deflection curve showed a bilinear model.Due to the higher utilization efficiency of BFRP bars as well as the high strength of RPC, the cracking load and the ultimate load of RPC beams were significantly higher than that of normal concrete beams. The new type RPC-BFRP beam showed a positive effect on both the flexibility and bearing capacity.
