Abstract
Abstract A foundation system for buildings and other structures absorbs both horizontal and vertical displacement from seismic earthquakes. The system comprises a fixed support base with a hardened three dimensional curved member located between a hardened dished top surface of the base and a hardened reverse dished cup on the underside of a concrete beam which has post tensioned members therein. The concrete beam is preferably cambered or curved and allows a certain amount of deflection and the three dimensional curved member, preferable an elliptical shape, allows horizontal displacement. In another embodiment the elliptical shaped curved member is formed in two halves with a spring in between to allow limited compression of the member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A foundation system for a building structure comprising: a plurality of pairs of fixed bases arranged to support the structure, the bases in each pair spaced apart and having hardened dished top smooth surfaces; a steel three dimensional curved member of elliptical shape, located in the dished top surface of each base, said curved member being formed in two halves with a spring means therebetween adapted to be compressed a limited amount; concrete beams, having post tensioned members therein, extending between bases in each pair and having hardened reverse dished cups on the lower surface at the ends of the beams, to rest on the curved member located in the dished top surface of each base, and support means for the building structure on the concrete beams between the ends of the beams.
Claim 2
Dependent Claim
