In recent years, wooden houses may be required higher seismic performance than before. Installing isolation system can be considered as one of the solution, whereas its cost prevents the promotion. This study presents a new isolation system without steel framed foundation by using continued columns and steels shaped like a dish; formed in a recess shape at the center which generates the force putting the structure back to there. This paper describes findings from both numerical simulation and basic experiments, and the behavior of new system can be explained.
