In this paper, two types of an earthquake isolation system based on the theory of the pendulum for wooden houses are investigated. One is a system consisting of linear bearing having a certain curvature to give the superstructure a proper natural frequency and the other is a friction pendulum bearing which has already been reported by one of the authors. The purpose of these systems is both prevention of overturning furniture and destroying house in itself. Both systems are based on the theory of the pendulum, and one of the most desirable isolation systems for light-weight structure, because a fundamental natural frequency of these systems is easily obtained by choosing a suitable curvature of the systems. In this study, response analyses are carried out to investigate the motion of a wooden house with these earthquake isolation systems against the severe earthquakes.
