Abstract

Experimental data obtained from strengthened, pre-cracked, reinforced concrete (RC) specimens are presented. Strengthening was attained by the adhesion of carbon fiber reinforced plastic (CFRP) sheets to the concrete surface. The CFRP was applied as done in situ (i.e. working under the beam). It is shown that the effect of CFRP strengthening was considerable. An analytical model has been used to simulate the load-deflection behavior as well as the failure mode of the pre-cracked RC specimens. Different failure mechanisms from ductile to brittle were simulated and verified by adopting the mechanical properties of the constituent materials. A description of two significant field applications concludes the paper by showing the feasibility of using the CFRP strengthening method.
