  • Periodic material-based seismic isolation system
    Patent number: 9139972
    Abstract: Periodic material-based seismic isolation systems and methods are a new and innovative means to mitigate the potential damage to structures due to earthquakes or the like. The periodic materials are arranged in a periodic way in one, two and three directions, which are defined as one-dimensional (1D), two-dimensional (2D) and three dimensional (3D) periodic materials. With this periodic material, the pattern of the earthquake event energy can be completely obstructed or changed when it reaches the periodic foundation of the structural system. This may result in a total isolation of the foundation from the earthquake wave energy.
    Type: Grant
