Seismic protection Product features mageba LASTO®LRB lead rubber bearings work on the principle of base isolation and limits 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. The rubber provides the isolation and re-centring of the bearing after a seismic event. The lead core deforms plastically under shear deformations, while dissipating energy through heat. Properties LASTO®LRB lead rubber bearings consist of alternate layers...
