Seismic isolation bearings

الوصف

Basically seismic isolation can be defined as reducing the effect of seismic action on the building through placement of isolation units which has high stiffness in vertical direction while very low stiffness in horizontal direction.

Seismic base isolation has been used with increasing popularity to protect structures, together with their occupants, secondary systems and internal equipment.Seismic isolation building technology that flexibly absorbs the shaking of an earthquake and protects the lifeline of the building. There are two ways to protect buildings from earthquakes: "seismic resistance" and "seismic isolation."

The main products of seismic isolation bearings include:lead rubber bearingsLRB, linear natural rubber bearings LNR,friction pendulum seismic isolation bearings FPB,high damping seismic isolation rubber bearingsHDR , andelastic slide bearings ESB.

They are commonly used in beam bridges, highway bridges, and railroad bridges.
