The current work discusses optimizing the structural design of reinforced high strength concrete rectangular sections under design loads. Using a least-cost design criterion and minimal design variables, an analytical approach to the problem is devised. A nonlinear mathematical programming format for the formulation of the problem is among the things that are demonstrated. To demonstrate how the formulation can be used in line with the ACI 318-08 standard, several typical cases are given. The outcomes are compared to those obtained from existing design practice. The ideal solution demonstrates unequivocally that significant reductions in the anticipated absolute costs of the building materials to be employed are possible and without making significant changes, this method may be expanded to address other portions.
