Publication Name Cost-optimum Design of Reinforced Concrete Beams based on Strength & Ductility & Serviceability Requirements and Practical Consideration
Publication DescriptionAn optimization procedural method for the design of rectangular beams is presented. The optimization procedure is formulated as finding the minimum cost of design with constraints imposed based on ACI code provisions. The cost of concrete, flexural reinforcement, and formwork is included in the formulation of the objective function. The behavioral constraints, i.e., ACI requirements for flexure strength, serviceability requirements, i.e., deflection, and practical constraints, i.e., cross-section dimensions of beams, are included in the formulation. A closed-form solution of the optimization problem expresses the optimal values of the flexure reinforcement and section dimensions in terms of material costs, strength and ductility parameters. A complete flow chart and a computer program of the algorithm is presented and several numerical examples are given to show the validity of the proposed optimization method.
