BS EN 1337-3 is the third part of the BS EN 1337 multi-series that discusses structural bearings.
BS EN 1337-3 applies to elastomeric bearings with or without complementary bearing devices to extend their field of use such as flat sliding elements covered by BS EN 1337-2 or sliding surface, as used in bridge structures or any other structure with comparable support conditions.
BS EN 1337-3 applies to elastomeric bearings with dimensions in plan up to (1200 x 1200) mm. BS EN 1337-3 applies to laminated bearings types A, B, C, laminated sliding bearings types E and D, plain pad and strip bearings type F.
BS EN 1337-3 deals with bearings for use in operating temperatures ranging from – 25 °C to + 50 °C and for short periods up to + 70 °C.
BS EN 1337-3 on elastomeric bearings is useful for:
Elastomeric bearings are widely used in bridge and building constructions. Elastomeric bearings are used to accommodate axial, shear and rotational movement. These bearings also help to accommodate thermal changes that might incur within the girders and help maintain the stability of the bridge.
BS EN 1337-3 provides you with functional requirements and performance requirements for elastomeric bearings. BS EN 1337-3 also provides you with test methods to verify that the bearings meet the requirements that include shear bond strength, compressive stiffness, ozone resistance etc. BS EN 1337-3 also helps you to design quality laminated bearings, plain pad bearings, strip bearings and sliding elastomeric bearings.
Overall, the guidelines of BS EN 1337-3 enable you to produce or incorporate quality elastomeric bearings with high load capacities for bridge-building projects.EN 1337-3:2005
