| Outline of Final Research Achievements |
This research aims to establish a basic method which can clarify structural characteristics of existing building structures and estimate seismic performance based on recorded vibration data. Especially, necessary theories are proposed which are applicable to old timber structures which are required urgent estimation of seismic performance and the validity of those theories are examined by numerical examples.
Newly developed techniques can be applied to timber structures with soft floor and complicated nonlinear structural performance which are one of the characteristics of timber structures or can be applied to timber multi storied structures even though responses are not recorded at some floors.
