| Outline of Final Research Achievements |
In order to evaluate the structural characteristics of traditional wooden buildings, this study was carried out with two processes; one is based on experimental, the other is based on observation records under strong motions. The experimental investigation is tried to assess the viscoelasticity based on stress relaxation of a bolt, which is set up through the wood specimens. The effectiveness and applicability of the test method was validated, and the viscoelasticity of wood on long relaxation time was evaluated by the test method. The examination on basis of earthquake observation is deal with as inversion problem. An analysis program based on subspace method, which is one of the system identification method, was constructed. By using this program, the stiffness of a part of target structure was evaluated.
