An experimental study of a base-isolation system using laminated rubber bearings and viscous dampers
Abstract
The authors have performed tests on their earlier developed base-isolation system, which uses laminated rubber bearings and viscous dampers. In 1984, we constructed a full-scale model (supporting 505 ton of weight), and, using this system, carried out a free vibration test. Twelve seismometers were installed in this structure, enabling us to observe its earthquake response. From the free vibration test, earthquake records, and a simulation analysis, we confirmed the effectiveness of the base-isolation system.
