  • Earthquake resistant building support system
    Patent number: 5181356
    Abstract: A building support system that resists horizontal forces resulting from earthquakes. Each support or group of supports is positioned on a horizontal planar base which allows limited horizontal movement of the support relative to the base. Each support is secured to the building being supported and each base is secured to the earth or building sub-foundation. Each support includes a damping arrangement for damping horizontal oscillations of the earth. Each base includes walls limiting horizontal movement of a support across the base and energy absorbers adjacent to the walls that engage supports approaching the walls. This system will accommodate both oscillatory earth movement and horizontal longitudinal movements.
