High Damping Rubber Bearing
High Damping Rubber Bearing
The high damping rubber bearingis a type of seismic isolators for buildings. This laminated composite rubber isolation bearing with high damping performance is made by adding various ingredients in the natural rubber. The high damping rubberbearing not only maintains the good mechanical properties of the natural rubber bearing, but also has a high damping ratio, which can effectively absorb the seismic energy in the earthquake and reduce the impact of the earthquake.
Features of High DampingBearings
Green and environmentally friendly;
No lead pollution.
Application of High Damping Rubber Bearing
This high damping rubber bearing is widely used in seismic isolation design and seismic reinforcement renovation of bridges, buildings, hydropower projects and other civil structures.
