Strength performance of deep beam with embedded side plates as shear reinforcement: A numerical analysis

Abstract

The major design criteria in deep beam is shear failure, as it is brittle in nature and causes sudden damage or collapse. Hence, research had investigated the effect of their shear strengthening method on the load carrying capacity of deep beam. This study proposed a method which replace the shear link with mild steel plate as an alternative shear reinforcement that reduce steel congestion in deep beam. Three numerical specimens were modelled using ABAQUS. The specimens were simply supported at both end and two-point loads were gradually acting on the specimens in the mode of monotonic loading condition. The results obtained from the numerical control specimen was validated with the experimental results done by other researchers. The numerical results show that the load bearing capacity of proposed deep beams were lower than the conventional specimen. The mild steel plates in proposed beams demonstrated tendency of side concrete cover separation from the main concrete body. Hence, it caused delamination of concrete leading to lower load carrying capacity.
