This paper presents the shaking table test results of two types of wooden house models and the rocking base-isolated model based on the earthquake accelerogram recorded during the Niigata-ken Chuuetsu (2004) earthquake. The wooden house models are two-story frame models with braces and seismic walls. The rocking base isolated device is composed of bearings arched in the lower part, steel balls and a stainless steel sheet. The experiments are carried out for sweep and two-direction vibration tests. In the sweep test, the first natural frequency of the two wooden models was 4.04 and 6.06 Hz. In the two-direction vibration test, the safety and base isolated models did not collapse, but the no-safety model collapsed due to the torsion vibration. Teaching materials of wooden house and an experimental video are introduced through disaster prevention education for junior high school students and citizens.
