Shear Resistance of Fibrous Reinforced Concrete Deep Beams with Opening – A Critical Review
Keywords:Reinforced Concrete Deep Beams, Shear Behavior, Steel fiber, Web opening
Reinforced concrete deep beams are more prone to shear failure. Thus, it is important to study the shear behavior for structural reinforcements. The presence of web openings in reinforced concrete deep beams is frequently required to provide accessibility such as doors and windows or to accommodate essential services such as ventilating and air conditioning ducts that affect the shear resistance. This research highlights the limited research on the shear resistance of fibrous reinforced concrete deep beams containing openings worldwide and illustrates their influence on shear behavior. This review has shown that the ultimate and the first cracking loads increase, increasing steel fiber content to a certain limit. End hooked steel fiber with 1.5% gave the highest shear resistance and ultimate load capacity compared with other types of steel fiber. Moreover, the stiffness of reinforced concrete deep beams increased with increasing fiber content from 0 to 1.5%. In addition, the effect of web openings on the shear strength of deep beams at the ultimate and cracking loads depends on the degree of interruption of the natural load path joining the loading.
