A new seismic isolation system using hemispherical sliding bearings to steel pipe pile foundation is proposed for the design of a house. Experiments were performed on model structures of a house with and without the bearings. With the bearings, the vibration of its roof was lower than that without the bearings, while an unexpected increase in vibration occurred on its floor. Detailed analyses identified that stick-slip occurred at the contact interfaces of the bearings and caused the increase in vibration.
