UPDATING A FINITE ELEMENT MODEL OF THE HUALIEN NUCLEAR REACTOR BUILDING

摘要

The updating, on forced vibration tests, of a dynamic model from the HUALIEN nuclear reactor building scale model is presented. The updating method is based on the minimisation of an error in constitutive relation. The tuning concerned soil impedances considered as a layer of viscous dampers and springs. Once updated, the model was in good agreement with experimental test data.
