Abstract:The effect of adding steel fibers to reinforced concrete corbels is investigated by tests on six specimens containing varying amounts of fibers. The shear span-span ratio was varied also, and all corbels were tested under vertical loading only. The results obtained from this study, together with some other available data, indicated a considerable improvement in the ultimate load-carrying capacity of corbels due to the addition of fibers. A comparison between the experimental results and predicted values by the ACI Building Code (ACI 318-83) provisions for corbels, truss analogy theory, and the method proposed by Fattuhi demonstrated the limitations and inadequacy of the three methods. It was concluded that the ultimate strength of reinforced concrete corbels with fibers can be predicted best by adding the fibers' contribution to the strength using the shear friction equation to the ACI Building Code provisions.
