Abstract

This study investigates the influence of seismic isolation technology on the floor response spectrum of Nuclear Island Building, addressing critical seismic safety concerns. Finite element modeling of the nuclear island building in ANSYS enables comparative analysis of dynamic responses between conventional and isolation structures under seismic loads. The results demonstrate that the isolation system can effectively prolong the structural natural period, reduce seismic energy input, and achieve integrated translational motion of the entire structure. Simultaneously, the seismic isolation technology can significantly reduce the horizontal floor response spectra of Nuclear Island Building, demonstrating notable attenuation effects in the high-frequency range. This study provides theoretical foundations and practical references for seismic isolation design in nuclear power plants, demonstrating significant implications for subsequent aseismic design and safety enhancement of equipment, piping systems, and related components.
