Abstract

In this research, the possibility of using concrete materials with tensile hardening behaviour (high performance fiber reinforced cementitious composites, HPFRCC) for strengthening RC beams is investigated. In order to verify the effectiveness of the proposed solution, full scale tests have been performed on 4.5 m long beams. A beams without any reinforcement and a beam with an ordinary reinforcement ratio equal to 0.03% have been strengthened with a jacket in HPFRCC having a thickness of 40 mm. A third beam with an ordinary reinforcement ratio and without jacket application has been used as reference specimen. The obtained results show the effectiveness of the proposed technique both at ultimate and service ability limit states.
