| Outline of Final Research Achievements |
An optimization method has been presented for designing a flexible support for preventing damage at the connection between long-span roof and its support sructure. A syncronized vibration of roof and support also prevents damage of nonstructural components such as ceiling. It has been shown that diagonal displacement of connection resuces seismic responses of arch in normal direction. Similar effect has also been confirmed for a long-span latticed shell. Furthermore, a support structure with upward displacement due to horizontal loads has been optimized considering geometrical ninlinearity to realize a base isolation utilizing geometrila nonlinearity. The effectoveness of this support has been confirmed by a small-scale model.
