Paper Title:
Investigation on Flexural Behavior of Reinforced Concrete Beams Flexurally Strengthened by Different Methods
  Abstract

Externally bonding fiber reinforcement polymer (FRP)laminate to the soffit of reinforced concrete (RC) beam is an effective way to increase its flexural strength. However, there is little investigation on flexural behavior of RC beam by side-bonding FRP laminates.To investigate the difference of flexural behavior between soffit-bonding and side-binding FRP laminates RC beams,a total of 9RC beams were tested, including 8 strengthened beams and 1 control beam. The test results showedthat:1) As fiber reinforced concrete, side-bonding FRP laminates can also effectively increase the first crack strength of RC beams.The first crack load improved significantly; 2) side-bonding FRP laminates is not a good method to improve the flexural behavior of RC beam at the yield stage and the post yield stage. 3) Side-bonding of CFRP laminates is a good way for existing RC beams to control its crack width and deflection.
