MetadataShow full item record
This paper introduces Genetic Algorithms technique to find an optimum formwork design, using optimum section of joists, stringers and shores along with their spacing, and satisfying minimum cost. Genetic Algorithms technique is based on the principles of natural selection and evolution, and it is used to solve optimization problems. This technique searches from a population of possible solutions that is limited by a set of constraints. The bending moment, shear, maximum deflection, and other imposed ACI code provisions, were used as constraints for the optimization problem. The Genetic Algorithms solution to the formwork design problem provides optimum design parameters such as the optimum cross section for form members, optimum spacing of form members, etc. The cost of material and labor involved in formwork erection are considered in the formulation of the objective function of the optimization problem. The method developed can be applied to the design of formwork for elevated slabs and high rise concrete elements.
