Charged System Search Algorithm for the Optimum Cost Design of Reinforced Concrete Cantilever Retaining Walls

In this paper, optimal design of reinforced concrete cantilever retaining walls is performed under static loads utilizing the charged system search (CSS) method. This design is based on ACI 318-05, and optimization is on the basis of cost function of materials used in retaining walls and their constructions. This function is minimized while satisfying the design constraints. Performance of the CSS algorithm is compared to that of the improved harmony search algorithm. Four examples are optimized and their convergence curves are compared.
