Pot Bearing

  • ATLAS POT BEARING

    ATLAS Pot Bearing is used for structures such as bridges and viaducts which are exposed to different rotational and displacement effects, and is designed according to EN 1337-5, AASHTO LRFD .

    POT BEARING WORKING PRINCIPLE

    ATLAS Pot Bearings consist of a steel pot, an elastomeric pad in this pot, and a steel piston element that transmits the vertical load and rotational effects of the superstructure on the elastomeric pad to the substructure.    odate rotational effects up to 0.03 radians by a viscous fluid motion in the pot.

    The horizontal and vertical forces transferred from superstructure are transferred to the pot by the piston. If required, pot bearings can make free horizontal movements in one direction or in all directions. 

    The horizontal movement is provided by a special PTFE material placed on the piston with low friction and high pressure resistance.

    DESIGN CRITERIA

    • Custom Designed for the project according to the required vertical and horizontal load carrying capacities
    • Has a rotational capacity up to 0,03 radians.
    • If required can be regulated for free horizontal movements in one direction or in all directions.
    • Has long service life under dynamic loads

    DESIGN STANDARTS

    ATLAS Pot Bearings are designed according to European Standards and has a CE Quality Certificate. If required, pot bearings can be designed according to AASHTO LRFD or other international standards.

    Standards used for design are:
    EN 1337 - 1 General Design Rules
    EN 1337 - 2 Sliding Elements 
    EN 1337 - 5 Pot Bearings
    AASHTO LRFD Bridge Design Specification
