Seismic Isolation Bridges

Supported by the seismic isolation bearings to cope with as large an earthquake as the Great Hanshin-Awaji class earthquake, the bridge will survive the earthquake with the elongated period of ground movement and damping effect.

The types of seismic isolation bridge products

  • Can satisfy the requirements for stable performance of bearings with supporting loads, allowing elongation and rotation of bridge girders over a long period of time.
  • Customized dispersion ratio of horizontal force during an earthquake will allow the bridge design to be more reasonable.
  • Maintenance is easier as compared with steel bearings.
  • Simpler structure provides with ease of replacement work.
  • LRB performance can be flexibly designed according to the size and the characteristics of the structure by adjusting the size of the lead plug.
  • Can satisfy the requirements for stable performance of bearings with supporting loads, allowing elongation and rotation of bridge girders over a long period of time.
  • Customized dispersion ratio of horizontal force during an earthquake will allow the bridge design to be more reasonable.
  • Maintenance is easier as compared with steel bearings.
  • Simpler structure provides with ease of replacement work.
  • High energy absorption reduces seismic force and displacement induced by an earthquake.
  • Compact size and rich lineup will allow the flexible arrangement of dampers with the required number and performance.
  • Provides an economical solution for anti-seismic reinforcement with less ancillary works.
  • Prevents the displacement of position or falling of the beam, shows an excellent performance against the earthquake.
  • Mainly used for the road bridge.
