Abstract
FBG sensors have excellent compatibility with CFRP sheets. It can be embedded into
CFRP sheets to fabricate the “smart” CFRP. This paper conducted 4 pieces of CFRP-strengthened
RC beams, and embedded FBG sensors and strain gauges on the steel, concrete and CFRP of RC
beams. The simulation program of flexural load effects of RC beams is compiled based on the theory
of reinforced concrete and ANSYS. The experimental results show that during the load bearing
process: the compatibility is perfect between FBG sensor and CFRP; the linear relationship of FBG
sensor and strain gauge is uniform; the numerical simulation results and the measuring results of
strains of tensile steel and compressive concrete, the load agree well. So utilizing the smart CFRP
strengthened RC structures can realize the dual function of advanced rehabilitation and real-time
health monitor and evaluation.
