Economical Design of Corbels

Abstract

This study is an application of optimization method to the structural design of corbels, considering the total cost of the corbel as an objective function with the properties of the corbel and shear span, dead load, live load and corbel width, as design variables. A computer program has been written to solve numerical examples using the ACI code equations and all new requirements and criteria in concrete design. It has been proved that the minimum total cost of the corbel increases with the increase of the shear span, and decreases with the increase of the friction factor for monolithic construction.
