Abstract

A 1:8 foundation model was designed and fabricated based on a spring vibration isolation steam-turbine generator foundation. The gravity was simulated through the hydraulic servo loading system, and the pseudo dynamic tests were carried out under the action of two different 7th intensity medium earthquakes and a 8th intensity rare earthquake. The results indicate that, under the action of different earthquakes, the acceleration amplification factors are all smaller, the inter-story drift angles of each story are in accordance with the specification requirements. Cracks appeared under the action of 8th intensity rare earthquake , but no penetrating cracks. Springs have played a good role in vibration isolation, and no relative slippages between the spring vibration isolator and the capital of columns.
