PERFORMANCE OF ONE-WAY REINFORCED CONCRETE SLABS WITH EXTERNALLY BONDED FIBER-REINFORCED POLYMER STRENGTHENING

Research is given from experimental work conducted on full-scale 1-way reinforced concrete (RC) slabs. 26 slabs with and without an overhang at 1 extremity were tested under simply supported conditions. The geometry and loading configuration allowed for the study of positive and negative moment regions. The slabs were strengthened with unidirectional carbon fiber-reinforced polymer (CFRP) laminates installed by manual lay-up. Different failure mechanisms--namely, concrete shear and crushing, CFRP rupture, and CFRP peeling--were obtained by varying the CFRP laminate cross-sectional area and amount of internal steel reinforcement. Findings from an analytical model that simulates and interprets the experimental results are also provided. These findings confirm the notion that peeling of the CFRP laminate affects the system performance but can be predicted by monitoring interface shear stresses.
