Abstract: The effect of laminate modulus on crack pattern, mode of failure and strength of shear deficient Reinforced concrete T-beam wrapped with FRP laminate is studied. Specimens of 2.5 m span, designed to fail in shear, were tested for two point static loading. Displacements, strains, and crack pattern were monitored. The strength and mode of failure are found to depend on the crack pattern. Laminate modulus increase is found to result in reduced web cracking and increased in web-flange junction cracking for U- wraps.
