The purpose of this paper is to estimate the vibration properties such as the natural period and the damping ratio of Japanese wooden houses subjected to strong ground motions. A subspace identification method is used to identify the vibration property from short-time acceleration data, and the variation of the vibration property during the earthquake ground motion is estimated. First, the validity of the proposed method is investigated through a numerical study. Then, the method is applied to the result of the three dimensional shake table test on a full-scale two-story wooden house. It is shown that the subspace identification method is effective to estimate the variation of the vibration property of wooden buildings subjected to strong ground motions.
