Abstract: An earthquake resistant building foundation includes a receptacle having a number of apertures each for slidably receiving a shaft, one or more spring members disposed below the receptacle for cushioning a vertical force, and a number of spring members engaged with the shafts for lateral cushioning purposes. A number of lateral cushioning devices are attached to the shafts and each has a casing secured to the shaft, a cover slidably engaged onto the casing, and one or more spring members engaged between the casing and the cover for cushioning between the casing and the cover and for forming a two-stage compressing or cushioning structure.
