Details about components of lead rubber bearing

Component of lead rubber bearingA diagram about the stable bilinear behavior of lead rubber bearing

With stable bilinear behavior

Features:


Stiff and strong in vertical direction but flexible in horizontal direction.

Absorb earthquake-generated force by changing the bearing's shape.

Allow the buildings to retain their original shapes and position owing to the high elastic force of rubber.

Capable to adjust damping amount just by changing the number of lead plugs.

Excellent vertical load capacity ranging from 5 tonf to 2000 tonf.

Reduce the ground acceleration by extending the structure vibration period.

High durable and elasticity of the rubber part - not suffer any damages during and after earthquake.

Easy to install without a separated damper.

Low maintenance.

With stable bilinear behavior shown as the above picture.
