An Experimental Study on the Shear Behavior of Reinforced Concrete Deep Beams Subject to Concentrated Loads

The shear behavior of simply supported reinforced concrete deep beams subject to concentrated loads has been scrutinized experimentally to verify the influence of the structural parameters such as shear span ratio, and the horizontal and vertical web reinforcements. A total of 27 specimens has been tested at the laboratory. In the tests all specimens have failed in shear causing inclined cracks from the load application points to the supports. The load bearing capacities have changed significantly depending on the shear span ratio. The effects of the vertical and horizontal reinforcements on the shear strength and crack initiation and propagation have been carefully checked and analyzed.
