Abstract
Presently it takes too much time and cost to construct large space systems such as the International Space Station. Sometimes we must modify or alter the mission and configuration of such system as required to comply not only with technical but also social or political affairs. Therefore basic concepts for future large space systems need to be able to adjust to such various changes. Also the life cycles of such space structural systems need to take account of such change. In this paper, hierarchical modular structure systems suitable for such future structures are proposed. These systems include structural shapes with properties of fractals. The proposed structural systems are composed of identically shaped modules which are hierarchically assembled using systematic rules. They can systematically form structures of various shapes and sizes. The geometrical aspects of modular space structures and two-dimensional and three-dimensional examples of hierarchical modular structural systems based on symmetry group are described.
