Analytical investigation of concrete beams reinforced with embedded CFRP plates

A detailed model and a nonlinear finite element analysis for concrete beams reinforced with embedded carbon fibre reinforced polymer (CFRP) plates, used as an alternative to FRP-bars, in a micro-model framework have been presented in this study. Bond relations between the CFRP plates and concrete ha...
