Abstract
This paper studies the optimization of beam-type rahmen structures simply-supported at both edges by Genetic Algorithm. In optimization, maximum deflection or maximum principal stress of the structure subjected a concentrated force is minimized under the constraint condition, where total volume of the structure is kept to be constant, by selecting optimal beam members of the structure. The deflection or stress of the structure is evaluated by using the finite element program developed for two-dimensional elasticity in this study, and optimal design solutions are obtained from numerical calculations by using the genetic algorithm employing binary coding, reproduction, crossover and mutation.
