Abstract:
Through a comparative study with test data obtained from an extensive literature survey, it is found that current code provisions cannot safeguard safe shear design solutions for structural elements exhibiting points of contraflexure. The cause of this is found to be linked with the formulation of the underlying theory, which has been calibrated with data obtained primarily from tests on simply supported beams. It is shown that an improvement can be achieved through the implementation of the detailing of the transverse reinforcement adopted by an alternative design method, which was found to provide a close fit to the test data in all cases investigated.
