碩士 === 國立交通大學 === 土木工程系 === 89 === In this study, a series of shaking table tests of a storage tank isolated with FPS has been carried out. The feasibility of using the friction pendulum systems for seismic isolation of storage tanks is confirmed, and adequacy of the proposed analytical model verified. Experimental results indicate that the friction pendulum bearing system provides effective seismic protection to the storage tank consistently under all types of earthquakes tested. It is found that the stronger the earthquake, the more pronounced the isolation effect, while higher storage level implies better isolation performance. Moreover, numerical simulations using the proposed hybrid structural-hydrodynamic model based on a rigid tank assumption show very good agreement with the test results, indicating sufficiency of this scheme in predicting the highly nonlinear structural-hydrodynamics of seismic sliding tanks.
