Floating seismic isolation building has been proposed as a measure to reduce seismic response of small modular reactor (SMR). Demonstration experiment on floating seismic isolation building was conducted in February 2024. Seismic response analysis model for OpenFOAM was built by reference to the demonstration experiment. To confirm the availability of the analytical model, the time history analysis was conducted using a sine wave with an amplitude of 0.05 m in the vertical direction and horizontal direction, respectively. This paper describes the overview of the analytical model and the results of Dynamic response analysis.
