Experimental Study on Floor Isolation of Main Control Room of Nuclear Power Plant using FPS(Friction Pendulum System)

마찰진자베어링(FPS) 면진시스템을 적용한 원전주제어실의 진동대 실험

The seismic characteristics with Friction Pendulum System have been studied using a shaking table system. In this study, we made two kind of floor system (Type I, Type II) and several seismic tests with and without isolation system were conducted to evaluate floor isolation effectiveness of Friction Pendulum System. Both type have showed large reduction effectiveness in acceleration, response spectra but Type II have showed lower acceleration and lower first mode in response spectra, compared to type I. On the basis of test results and consideration of application, it is found that type II is more suitable for floor model of main control room of Nuclear Power Plant.
