摘要：
Research on the behavior of RC beams shear-strengthened with EB FRP under long-term cyclic loading (fatigue) is relatively few and rather limited. The present study has examined two CFRP shear strengthening systems by comparing their effectiveness in extending the fatigue life of RC structures for increased live load (U-wrap sheets versus L-shape laminates). Laboratory tests performed on full-size RC T-beams were conducted. The results confirmed the feasibility of using both EB CFRP systems for shear strengthening under cyclic loading. They also showed an enhanced fatigue behavior of specimens when strengthening with L-shape laminates compared to U-wrap sheets.
