THE EFFECT OF BEAM SIZE ON SHEAR STRENGTH OF REINFORCED CONCRETE DEEP BEAMS
The objective of this study is to investigate the effect of beam size on shear strength of deep beams using finite element simulation. The beams considered have shear span to depth ratios between 0.76 and 1.4 and the overall depth varies from the 400 mm to 700 mm. In order to validate the FE simulation, a reinforced concrete deep beam the test result available in literature are used and the results from finite element have been compared with the test values and good agreements are obtained. The results showed reliability of analysis in predicting deep beams shear strength in terms of failure load and failure mode. This paper presents the result of finite element analysis RC deep beams conducted on thirteen simply supported reinforced concrete deep beams. The analysis was performed principally to investigate the effect of beam depth (overall depth) on shear strength of reinforced concrete deep beams. The behavior of deep beams including load-deflection curve, load-ultimate shear strength curve, and plastic strain-ultimate shear stress curve, shear failure modes of models, diagonal crack and ultimate shear strength, ultimate shear load capacity and diagonal strain and shear ductility has been investigated. The shear strength was found to decrease with increase of beam size and large size beams exhibited brittle failure, which was attributed to size effect. Increasing beam depth in deep beams turned ductile failure in to brittle failure. As beam depth increase shear ductility decreases in deep beams. In addition, failure mode of the deep beam changes from shear failure to concrete crushing due to compressive stress at the top corners of reinforced concrete deep beams as depth of the beam increases.
