Conference paper


The concept of frequency band gaps in periodic materials has inspired the development of a new type of seismic base isolation system known as the periodic foundation. This paper focuses on the experimental validation of the 3D periodic foundation supporting a small modular reactor building. A large-scale 3D periodic foundation with a small modular reactor (SMR) building model was tested on a shake table using various input waves. The frequency band gaps of the test specimen were able to filter out the damaging frequency content of the input seismic waves. The test results motivate the application of periodic foundations for safer nuclear structures in seismic-prone regions.
