ABSTRACT:
Apparatus for limiting the effect of vibrations between a structure and its foundation having two types of elastomeric load bearing pads. One pad has the capability of absorbing vertically and horizontally applied forces. The other pad has the capability of accommodating sliding motion between the structure and the foundation and additionally to absorb horizontally applied forces. The apparatus includes restraining means for limiting horizontal and vertical displacement of the structure with respect to the foundation for reducing failure of the elastomeric load bearing pads resulting from deformation caused by the applied forces.
