Seismic protection Product features mageba LASTO®HDRB high damping rubber bearings work on the principle of base isolation and limit the energy transferred from the ground to the structure in the event of an earthquake. The rubber and steel laminated bearing is designed to support the weight of the structure and to provide post-yield elasticity. Rubber provides the isolation and the re-centring of the bearing after a seismic event, while reaching higher damping of up to 16%, as compared to only 5% provided by conventional elastomeric bearings. Properties LASTO®HDRB high damping rubber...
