Assessment of stiffness and structural behavior of reinforced concrete beams rehabilitated with CFRP and crack injection
abstract: In this paper, an experimental program was developed in order to evaluate the structural behavior of RC beams rehabilitated with CFRP sheets and crack injections. The specimens’ stiffness before and after structural rehabilitation was assessed through vibration tests. Bending tests were employed to obtain load-deflection curves and evaluate failure modes. Results indicate that all beams displayed higher stiffness values after structural rehabilitation. The CFRP sheet fostered an increase of the specimens’ ultimate load. Crack injections influenced stiffness but did not affect the ultimate load.
