Isolation System

DRB’s seismic isolation system can disperse the vibration of the structure more effectively and exponentially increase the seismic energy to prevent damage. DRB provides a 100% domestically developed technology in the form of combined solutions for earthquakes, including development, production, construction, structural optimization etc.

Natural Rubber Bearing(NRB)

As it is laminated rubber made of natural rubber, it has excellent restoring force.

Features

  • It has low attenuation (the equivalent attenuation constant is 2~3%), excellent linearity and stable restoring force.
  • A design with a high degree of freedom is allowed for types of dampers and adjustment of attenuation.
  • It has almost no dependency on changes in axial force and displacement history.
  • It maintains stable rigidity despite large deformation.

Lead Rubber Bearing(LRB)

As it uses lead plugs with high attenuation, it possesses both attenuation and restoring force at the same time.

Features

  • It uses lead plugs with high attenuation
  • The natural laminated rubber fuctions as a spring, and the lead functions as a damper.
  • It is easy to install without a separate damper.
  • It is possible to adjust damping amount by controlling the number and size of lead.

High Damping Rubber Bearing(HDRB)

As it is laminated rubber made of specially mixed high damping rubber, the rubber itself has damping capacity.

Features

  • It is laminated rubber with high damping rubber
  • Rubber materials play the functions of both springs and damping materials themselves.
  • It is easy to install without a separate damper.
  • Its hysteresis curve remains relatively smooth.
