Seismic protection mageba seismic protection devices – for reliable preservation of structures LASTO®LRB Lead Rubber Bearing proven, safe, versatile

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 of...

Seismic protection Properties & benefits Materials The following materials are used for the production of mageba LASTO®LRB lead rubber bearings: • Reinforcing plates, the top and bottom plates are made from rolled carbon steel conforming to ASTM A36 or A570 • Natural rubber, type NR, grade 3 per ASTM D4014-81 Benefits • Significant dissipation of energy during earthquakes leading to an optimized structure size and reduced structure cost • Combined transfer of service and seismic loads leading to minimal space requirement for the devices • Lead with a minimum purity of 99.9% • Effective solution...
