  • Products Seismic Isolator for Buildings Bridgestone

    The Seismic Isolating Rubber Bearing consists of alternating laminations of thin rubber layers and steel plates (shims), bonded together to provide vertical rigidity and horizontal flexibility. Vertical rigidity assures the isolator will support the weight of the structure, while horizontal flexibility converts destructive horizontal shaking into gentle movement.

    In use, natural rubber has proved superior to all other rubbers as bridge bearing material. The design and positioning of the bridge bearing allows the vertical loads (deck and traffic) to be taken by the rubber in compression and horizontal deflections (expansion and construction) by the rubber in shear. High vertical stiffness is achieved by the insertion of horizontal metal plates, which do not alter the required low

  • Lead Rubber Bearing for Bridge or Buildings

    Comparison of the lead rubber bearing and common rubber bearing The damping coefficient of plain elastomeric bearing is less than 5%, while the lead rubber bearing is more than 15%. During the earthquake, the lead rubber bearing can increasingly reduce the accelerated speed and uniformly change the large force of the bridge superstructure, thus, lead rubber bearing has better seismic function.
