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.
