摘要： Apparatus for limiting the effect of vibrations between a building structure and its foundation is disposed between the foundation and the building structure. A plate is fixedly secured to a lower surface of the building structure. A hollow member having a rectangular cross-section is fixedly secured to the plate. An elastomeric bearing is disposed between and fixed to the hollow member and an upper surface of a foundation. A cable, anchored to the foundation, is centrally disposed within the elastomeric bearing and the hollow member, and has a stop attached to the free end thereof. The stop is disposed within the hollow member. The stop serves to limit horizontal and vertical movement of the elastomeric bearing. In a modified apparatus for limiting the effect of vibrations between the building structure and the foundation, an elastomeric material is disposed between the stop and the base of the hollow member to distribute a load applied by the stop through the deflection of the elastomeric material.
