Title: Shear Strength of Reinforced Concrete Beams Without Web Reinforcement
Author(s): F. J. Van Den Berg
Publication: Journal Proceedings
Appears on pages(s): 1587-1600
Abstract:Data are presented on the shear strength of 44 supported beams. Tests were carried out in four seris with the following variables (1) concrete strength shear span, (3) ratio of shear span to effective depth of beam and the effect of end-anchorage, and (4) percentage of tension reinforcement. The beams were tested under two symmetrical concentrated loads. All the beams failed in shear after diagonal tension cracks formed in the region of maximum shear. The magnitudes of loads causing initial diagonal tension cracks depend on the strength of the concrete, the percentage tension reinforcement ratio of shears panto effective depth and the cross section of the beam. The results indicate that the strength of beams with a/d ratios greater than two may be governed by the load causing the first main diagonal crack.
