Japan is one of the most earthquake-prone countries in the world, and there are concerns about the safety of current nuclear power plants. Therefore, the development of SMR (Small Modular Reactor) with high safety rationality is promoted. However, an appropriate seismic isolation system for SMR has not been determined. Therefore, we will study a seismic isolation system using laminated rubber. In this study, the nonlinearity in the large deformation region of laminated rubber is introduced into the analysis model and its influence is evaluated.
