Seismic isolators – RESTON-PENDULUM

Principle

mageba seismic isolator RESTON-PENDULUM bearings are based on the functional principle of a pendulum. They allow a structure to become horizontally displaced during an earthquake, with seismic energy being dissipated by the friction between various moving components. After the earthquake, the curvature of the sliding surface of the base causes the supported structure to return by gravity to its original position.

Applications

RESTON-PENDULUM seismic isolators can be used in the construction of new structures, or to enhance an existing structure’s strength and resistance to seismic forces. Under normal conditions, in combination with additional horizontal force bearings or dampers, they function as bearings, transmitting vertical forces and accommodating displacements and rotations. A significant advantage of this type of isolator over elastomeric types is its fire resistance.
