Technical guide – Pot bearings
Use on bridges, viaducts and similar structures
This technical guide is intended essentially for bridge designers. It provides the information required for the design of elastomeric pot bearings for use on road bridges and viaducts, footbridges and similar structures.
This document essentially comprises :
* a brief description of the product category and of the associated equipment;
* the key regulatory texts;
* the design criteria based on the normative texts prepared by the CEN;
* a calculation methodology for its use in a bridge project
This technical guide is intended essentially for bridge designers. It provides the information required for the design of elastomeric pot bearings for use on road bridges and viaducts, footbridges and similar structures.
This document essentially comprises :
* a brief description of the product category and of the associated equipment;
* the key regulatory texts;
* the design criteria based on the normative texts prepared by the CEN (European Committee for Standardization);
*a calculation methodology, not for the product itself, but for its use in a bridge project, with a concrete example based on an actual case.
