| Outline of Final Research Achievements |
Prestressed spatial structures, including membrane structures, cable-domes and tensegrity structures, are very light due to the introduction of prestress in their structural elements. Hence, they can be used as long-span structures to cover a very large space withouth columns, and they are very strong in earthquakes.
However, it is difficult to determine their (self-equilibrated) configurations as expected by the designers due to the existence of prestress; and moreover, their stability at self-equilibrium state and buckling behavior while subjected to external loads are great concerns in the design of these structures. In this study, we are to present novel design methodologies for these problems, especially making use of their symmetry.
