ABSTRACT
Shear capacity evaluation has remain a challenging task due to complexity of shear transfer compared the flexural capacity because of various affecting parameters. The state-of-the-art review is done about the shear mechanism, shear failure patterns and theories related to shear analysis. Various shear models with due assumptions have been developed based on lower-bound plasticity theory which rely on stress redistribution with steel reinforcement. But, lower-bound plasticity theory cannot be applied to the concrete elements with brittle FRP reinforcements. It is summarized that the realistic approach towards the shear capacity with FRP reinforcement which considers the compatibility, equilibrium and the material constitutive laws in combination like crack-based analysis reviewed in the paper.
