For an LRB, a lead plug is inserted into the center of the elastomeric bearing to absorb and scatter the horizontal energies generated during an earthquake.
When an earthquake occurs, an LRB can extend the natural period of a bridge and reduce the horizontal power caused by the weight. It can be a guideline to economical lower structure designs.
* LRB Features *
- An LRB can resist against short-term weights such as wind power or braking load by utilizing the elastomeric stiffness of lead. It has stability against all time weights. It easily adjusts to slow displacement such as temperature displacement and does not deliver large weights to the lower structure.
- By using the plastic deformation property of lead, it absorbs and scatters the earthquake energy.
- It can restore its original position after earthquakes are stopped. No additional repair or maintenance required.
