Description: 

High damping rubber bearing（HDRB） is made of special rubber with excellent damping attribute and sandwiched with reinforcing steel plates. The damping ratio can approach to 15% - 20%.

Features：

•  Strong capacity of horizontal displacement. 

•  Can absorb the earthquake energy effectively

•  Strong structural reduction ability makes little residual displacement 

•  With high damping material, it has good energy dissipation capacity

Types: 

•  Rectangular bearing

•  Cylindrical bearing

Design and fabrication standard:

•  JT/T 842-2012 High damping seismic isolation rubber bearing for highway bridges

•  GB 20688.3 Rubber Bearing - Elastomeric seismic protection isolators for buildings

•  In reference with EN 1337-3

•  In reference with EN 15129

Certificate:

•  CE Certificate of Constancy of Performance - Anti-seismic device (Elastomeric Isolators, type :HDRB) under the standard of EN 15129: 2009

•  ISO 9001 Certificate - Quality Management System
