Flexural performance of concrete beams reinforced

2019-5-1  FRP-RC beams failed by concrete crushing, achieving higher flexural capacity and larger deflection than the steel-RC beam. The use of FRP bars grouted in corrugated sleeves in tension zone of beams was an effective way to reduce crack widths and improve serviceability performance.

Effect of steel and synthetic fibers on flexural behavior ...

2012-4-1  This is because the large crack width and deep crack propagation in FRP bar-reinforced concrete beams have a high potential for the corrosion of steel fibers at cracks, even if crack widths of less than 0.1 mm do not allow the corrosion of steel fibers passing across the crack . This study focused on the flexural behavior of these beams in terms of load-carrying capacity, cracking pattern, and ductility.
