Though the optimization of size and shape has been widely applied in structural design, a new technique of the structural optimization, "topology optimization", is introduced recently, and it has been applied to the architecture and automobile design. In this study, the double bottom construction of a bulk carrier was taken up as an example of complex grillage structures, which consisted of floors and girders, and the topology optimization was examined. The double bottom construction was modeled as a boundary supported structure loaded by water pressure. According to the calculation results, unnecessary parts of the floors and girders to keep the rigidity were removed, and necessary parts were reinforced. By the analysis, the optimum structure, which has enough rigidity and less light-weight, was proposed.
