| Abstract |
The purpose of this study is to evaluate the flexural strengthening performances of the reinforced concrete flexural members strengthened by iFRPP(incombustible Fiber Reinforced Polymer Panel). The bond characteristics of iFRPP on the concrete were estimated to acquire the effective bond length for strengthening of RC members through various bonding tests. Also, full-scale RC beams strengthened by iFRPP were tested monotonically to evaluate the strengthening effects of iFRPP on the RC beams. The main variables of the six test specimens were the thickness of iFRPP and bond length. From the test results, it was found that the failure mode of RC beams strengthened by iFRPP was governed by the fracture of iFRPP, and flexural strengthening effects of iFRPP on the RC beams are proportional to the thickness of iFRPP. Therefore, the bond strength of 5.0kgf/㎠ and the partial reduction factor of 0.9 for the strengthening design of RC beam is proposed in this study. |
