| Abstract |
Space frame system is applied to various parts of large spatial dome structures. Especially, space frame dome structure is composed of traditional shape or the combinations of various shapes and new design. In this case, the big difference in the total weight and behavior of structures is shown, based on the selection of space frame dome structure and the difference of member connection, even if they have same size and height. For this reason, it is not easy to decide the optimal shape in the design of this system. Therefore, this study presents the shape generation method and then try to develop the shape generation module. To this end, the node and member generation technique is formulated to consider the characteristics of shapes through the various example selection of space frame dome structure. Also, various example models are presented for efficiency evaluation of the shape generation technique and optimization results are compared through the application of optimization algorithm. |
