This paper presents layout (topology, shape and node position) optimization, under stress constraint, of trusses whose members are described as the discretized cross-sectional areas by using genetic algorithm (GA). The size optimization problems were successfully solved by hybrid method combining GA with fully stressed design (FSD), and the result was reported in the previous paper. In this case, the cross-sectional areas of the members, the topology (i.e. the arrangement of the members), where the members assigned with extremely small cross-sectional areas are considered "not to exist", and the positions of the nodes are chosen as design parameters. The hybrid method are tested for four kinds of the structures with convergence parameters varied in FSD. From the test results the Authors confirm that the hybrid method is efficient and stable in search for globally optimal layout, in layout optimization.
