This paper studies the topology optimization of cantilevered beam-type, extruded aluminum structures subjected to multiple loadings by genetic algorithm. In optimization, maximum deformation of the structure is minimized under a constraint condition, where total number of inner ribs within the structure is kept to be constant, by selecting the locations of the ribs. The deformation of the structure is evaluated numerically by using the finite element analysis developed for two-dimensional elasticity in this study, In numerical calculations optimal design solutions are obtained for the structures subjected to multiple loadings of bending, shearing and stretching.
