Most of non-rubber type isolation systems apply frictional force. One of the famous non-rubber type isolation systems is Friction Pendulum Bearing ( : FPB) system. 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, the behavior of the structure and the isolation systems in considering the dispersion of the friction coefficient of the each device and vertical load on the each device is examined during earthquake. In this report, The analytical models used the existent isolated building and the square structure, and these models are considered as rigid body models. The dispersion of the friction coefficient and vertical load is made to occur from the normal random number. The behavior of the structure and the isolation systems during the earthquake was stochastically investigated using a Monte Carlo method.
