Reinforced concrete corbels have become a frequent attribute in building construction, with precast high-strength concrete increasing use. Corbels are short-hunched cantilevers that project from the inner face of columns or walls to support heavy concentrated loads or beam reactions. They are essential structural elements for supporting precast beams, girders, cranes, and other precast structure systems. This paper reviews the effect of fiber, shear span to depth ratio, concrete strength, and reinforcement ratio on the reinforced fibrous high strength concrete corbel's shear resistance in previous research. The results show that the shear resistance of corbels enhances with increasing main reinforcement, compressive strength, and the volume fraction of fibers, whereas it decreases with the improvement of the shear span-to-effective depth ratio of the corbel. In addition, using fibers in high-strength reinforced concrete corbel increases the ductility and thus defines the mode of failure of the corbels, depending on the fiber parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
