Seismic Rubber Bearing 


Seismic Rubber Bearings / Lead-Rubber Bearing is one of earthquake isolator Bearing types. Sticking its’ main structure multi-storey thin rubbers and steel planes layer by layer can make its’ pad close together. Let lead be pressed into the central hole of bearing and inlay it between steel and rubber layers. Layer by layer rubber can isolate earthquake because it can provide vertical bearing and elasticity and supple ability of horizon direction. It can absorb earthquake energy using changed shape caused by the pure shear yield of lead. It contains many functions combining bearing and earthquake isolator perfectly.
Seismic Rubber Bearings / Lead-rubber bearing is made from layers of rubbers sandwiched together with layers of steel. In the middle of the bearing is a solid lead " plug. " On top and bottom, the bearing is fitted with steel plates which are used to attach the bearing to the building and foundation. The bearing is very stiff and strong in the vertical direction, but flexible in the horizontal direction.

What Type the Structure are use The Seismic Rubber Bearing / Lead Rubber Seismic Isolator :
Hospitals, Bridges and Emergency centers that require operation during and immediately after an Earthquake
structure with valuable contents or operation such as : data centers, communications facilities, high-tech manufacturing and museum
Buildings with high occupancy such as low to – medium rise residences and office buildings
Historic structure, etc
The Gada` s Seismic Rubber Bearing is available with a range of Rubber properties from low damping rubber to a high damping rubber or with a lead pluq making a lead rubber bearing.The Gada` s Seismic Rubber Bearing is also available as a “ Hybrid Bearing” with a high damping rubber plus the lead plug providing many of the advantages of both models.
