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.
Claims4
An earthquake resistant building support system which comprises:
- a base means adapted to be secured to the earth below a building;
- a substantially horizontal planar upper surface on said base means;
- an upstanding wall surrounding said base means;
- building support means adapted for connection to and support of at least a portion of a building, said support means comprises a body having a cavity therein extending to one end surface with an opening at said one end surface, said one end surface being positioned adjacent to said planar upper surface of said base means;
- a groove surrounding said cavity in said one end surface;
- an O-ring of elastic compressible material secured in said groove;
- means for introducing gas under pressure into said cavity, said gas under pressure contained within said cavity by said O-ring and means at the end of said body opposite said opening of said cavity for attachment to a building to be supported;
- said support means adapted to rest on said base upper surface for sliding movement relative thereto;
- spring means along said base wall and normally spaced from said building support means to absorb energy and prevent direct impact in the event that said relative sliding movement brings said wall and support means together.
