  • Vertical vibration control device
    Patent number: 5433045
    Abstract: A device to control vertical vibration of a building caused by seismic disturbance. Air springs are positioned and secured between the building foundation and the building superstructure to attenuate vertical vibration of the building. Vertical support rails are secured to the foundation and/or to the building superstructure on opposite sides of, and adjacent to, the air springs. Horizontal connecting brackets are rigidly secured to the air springs and slidably secured to the adjacent rails. The brackets restrain horizontal deflection of the air springs without interfering with vertical reciprocation of the air springs.
