After the Hanshin-Awaji Earthquake Disaster, the number of earthquake isolated buildings are increasing with a great dominance. Even though most of the base isolated buildings or structures are built on laminated rubber bearings to give them certain natural periods, this situation also encourages structural engineers to research and develop non-rubber type isolation systems such as linear bearing isolators and friction pendulum systems. When using friction pendulum system in the open air circumstances, some have pointed out that long term durability of the systems must have been taken into account and it might have been very difficult to maintain the friction coefficient. In this study, dynamic motion of the isolated structure model with 4 of Friction Pendulum Bearing (FPB) systems are investigated, especially in in-plane mode, considering a variance of friction coefficient of one system, a distribution of the mass of superstructures and so on. The shake table test using 3-storey steal-frame model was carried out. The comparison of the result of excitation test and analysis using rigid slab model presented in this report.
