REINFORCED ELASTOMERIC BEARINGS acc. EN1337-3
Reinforced elastomeric bearings are made of a special rubber blend and are equipped with reinforcement steel sheets during the manufacturing process, the so called
vulcanisation. The steel sheets provide the necessary stiffness.
Reinforced elastomeric bearings stand out through their low maintenance and durability. Besides that, some types can be used under certain conditions without any additional steel structure (restraining). The elastomeric part of the bearing is elastically deformable.
The deformation rate in vertical direction (deflection) under permanent load is calculable and stays constant. The influences of live loads are generally small and the additional temporary deflections caused by live loads are of a minor degree and will cause no problems for most structures.
