Structural bearing pad E-SAFE : LRB

anti-vibrationseismicelastomer

AGOM antiseismic elastomeric devices, called E-Safe, are built to withstand vertical loads and simultaneous deformation in any direction, while allowing for minor rotations in any of the bearing’s axes. They are inserted between the base of the structure and its foundations, in order to reduce acceleration to a target value so as to avoid structural damages and to keep the relative displacement between the ground and the structure to acceptable values. AGOM E-Safe seismic isolators are generally characterized by high stiffness in case of small displacements, behaving like fixed points in order to prevent movements due to wind, etc., and by a low stiffness under large displacements in order to react and to absorb wide oscillations. After an earthquake the restorative properties of the rubber layers return the building to its original position. Elastomeric seismic isolators type LRB consist of a reinforced elastomeric bearing with one lead cylinder inserted in their core that provides very effective damping during extreme movements. The horizontal loads are transferred from structures to bearings by means of steel bars or screws bolted to the external plates.
