Abstract: Corbels are sections that project from the essences of columns and are used widely in precast concrete construction to support primary beams and girders. On account of the predominance of precast concrete, the design of corbels has become increasingly important. In this paper, a simple analytical expression is proposed for predicting the shear strength of reinforced concrete corbels using “Strut-and-Tie” Model. The proposed expression is compared with some of the existing expressions and ACI 318-14 code. The 178 corbels specimen’s experimental data has been collected from the literature and find out the unknown parameters. The proposed model accounted for compressive strength of concrete, shear span -to-depth ratio, breadth and effective depth. The results indicate that proposed expression as one the best fitting expression to predict the shear strength of RC corbels.
