Simulations of shaking table tests are conducted for this rigid mass, and also for the steel frame model which is conducted by ENEL/ENEA. Acceleration time histories, displacement time histories of the isolators as well as cyclic loading test data of the LRB used for the shaking table test are provided to the participants of the CRP. Shaking table test conducted by CRIEPI is of a base isolated rigid mass supported by LRB. Simulation results for these rubber bearings show satisfactory agreement with the test results. As for lead plug material in LRB, mechanical characteristics are reevaluated and are made use of. Several strain energy functions are specified according to the rubber material test corresponding to each rubber bearing. Using computer code ABAQUS, numerical simulations of rubber bearing tests are conducted for NRBs, LRBs (data provided by CRIEPI) and for HDRs (data provided by ENEA/ENEL and KAERI). In this paper outlines of the test data provided and the numerical simulations of bearing tests and shaking table tests are described. Test data concerning rubber bearing tests and shaking table tests of base-isolated model conducted by CRIEPI are provided to the participants of Coordinated Research Program (CRP) on 'Intercomparison of Analysis Methods for predicting the behaviour of Seismically Isolated Nuclear Structure', which is organized by International Atomic Energy Agency (IAEA), for the comparison study of numerical simulation of base-isolated structure.
