简介
This paper presents the results of a feasibility study to investigate the flexural behavior of structurally damaged full-scale pretensioned concrete slabs retrofitted with bonded carbon fiber reinforced plastic (CFRP) laminates. The effect of CFRP laminates bonded to the soffit of precracked solid and voided slabs is investigated in terms of flexural strength, deflections, cracking behavior and failure modes. The results, generally, indicate that strengthening of significantly cracked slabs by bonding CFRP laminates is structurally efficient and that the retrofitted slabs are restored to stiffness and strength values nearly equal to or greater than those of the original undamaged slabs. The results indicate that the retrofitted slabs maintained adequate structural integrity and composite action at all stages of testing up to failure.
