||A method to design cost-optimum slab formwork components is proposedin this paper. Genetic Algorithms (GAs), a technique based on theprinciples of natural selection and evolution, is applied to solve theoptimisation problem. GAs search from a population of possible solutionslimited by a set of constraints. The cost of form components and laborinvolved, were considered for the formulation of the objective function ofthe optimisation problem. The bending moment, shear, maximumdeflection, imposed ACI code provisions, etc., were used as constraints forthe optimisation problem. Application of GA to the formwork designproblem provides optimum design parameters such as the optimum crosssection for form members, optimum spacing of form members, etc., whileminimising the total cost. Formwork made either from wood, wood-metalcomposite or metal alone can be designed using the proposed technique.The paper presents the case of general formwork design, however, themethod as a whole readily applies to the design of formwok for elevatedslabs and high rise concrete elements.
