HARMONY SEARCH ALGORITHM FOR OPTIMUM DESIGN OF SLAB FORMWORK

Abstract– In this paper, harmony search algorithm is utilized for the optimum design of slabformwork. This method is a numerical optimization technique developed recently that imitates the musical performance process when a musician searches for a better state of harmony. The cost of the form components involved is considered as the objective function of the optimization problem. Constraints for the optimization problem are bending moment, shear, maximum deflection and imposed ACI code provisions. The use of the harmony search to formwork design problems provides optimum cross sections and optimum spacing of the form members (joist and stringer), while minimizing the total cost.
