The test specimens were experimented under constant compressive load and controlling the lateral displacement angle. The test specimens with round main reinforcements did not brake with shear failure due to very small bond stress of the main reinforcements, and a state of the shear compressive failure by the slippage compressive failure on the diagonal of the concrete appears conspicuously. Therefore, the relationship between shear load and the lateral displacement angle showed a property of ductility without the yield strength deterioration to 0.032 rad after maximum load although it almost showed the hysteresis curve of a remarkable reverse S-shaped. The maximum strength obtained from by a plasticity theory considering of a truss mechanism and an arch mechanism.
