U-shaped Damper Integrated with Laminated Seismic Isolation Rubber Mount

U-shaped Damper Integrated with Laminated Seismic Isolation Rubber Mount

Laminated Rubber Integrated with a U-shaped Steel Damper

This is a U-shaped damper integrated with a laminated seismic isolation rubber mount. This is a steel damper made of high quality rolled steel. By combining with laminated rubber, the number of installed dampers can be reduced.

  • High Quality

    When an earthquake occurs, this absorbs the seismic energy and reduces seismic vibrations using its property of stable restoring force. This mount also has an excellent fatigue-resistant property for repetitive vibrations.

    High Design Flexibility

    It is possible to design the best seismic isolation system according to shapes of buildings as any combination of size and quantity of U-shaped seismic isolation dampers are possible.

    Non-directional Feature

    The U-shaped seismic isolation damper exhibits almost identical historical properties in all directions of 360 degrees.

    Low Cost

    This is economical as the cost per yield shearing force is low.

    Easy Maintenance

    In the case of laminated seismic isolation rubber mounts integrated with U-shaped dampers, the damper and the laminated rubbers are separated and it is easy to visually confirm the level of damage after an earthquake. This simplifies maintenance work after the earthquake. It is also easy to change the damper after an earthquake if required to do so.

  • There are 4 types of laminated seismic isolation rubber mounts integrated with U-shaped dampers. Their usage can be determined by the positions of columns as shown below.

    • 4T type
    • 4Ntype
    • 4L type
    • 8Ntype
