Structural bearings - Part 1: General
This document specifies general rules for design, manufacturing, protection, transport, storage, installation, and inspection of structural bearings for use in bridges and other structures, e.g. buildings.
This document does not give rules for:
- bearings subjected to uplift forces;
- bearings for the specific moving function of moveable bridges (for example bascule bridges, lift bridges, etc.);
- concrete hinges;
- levelling pads.
It can be used for guidance in the case of temporary bearings and the principles can be applied to the design and manufacture of other types of structural bearings not included in this European Standard.
If bearings are used as or as part of anti-seismic devices with the aim of modifying the dynamic response of the structure, EN 15129 also applies.
This document will be used in conjunction with the other relevant parts of the prEN 1337 series.
Lager im Bauwesen - Teil 1: Allgemeine Regelungen
Dieses Dokument legt die allgemeinen Vorschriften für die Gestaltung, die Herstellung, den Schutz, den Transport, die Lagerung, die Installation und die Inspektion von Lagern im Bauwesen für den Einsatz in Brücken und anderen Bauwerken wie etwa Gebäuden fest.
Dieses Dokument gilt nicht für:
- Lager, die Sohlenwasserdruckkräften unterliegen;
- Lager für die jeweilige Bewegungsfunktion beweglicher Brücken (z. B. Klappbrücken, Hubbrücken usw.);
- Betongelenke;
- Nivellierfüße.
Das Dokument kann als Anleitung für temporäre Lager verwendet und die Grundsätze können auf die Gestaltung und Herstellung anderer Arten von Lagern im Bauwesen, die nicht in dieser Norm enthalten sind, angewendet werden.
Wenn Lager als Erdbebensicherung oder Teil einer Erdbebensicherung verwendet werden, um die dynamische Reaktion des Bauwerks zu ändern, gilt ebenfalls EN 15129.
Dieses Dokument wird in Kombination mit den anderen relevanten Teilen der Normenreihe prEN 1337 verwendet.
Appareils d’appui structuraux - Partie 1 : Indications générales
Le présent document spécifie les règles générales de calcul, de fabrication, de protection, de transport, de stockage, d’installation et d’inspection des appareils d’appui structuraux destinés à être utilisés dans la construction de ponts et d’autres structures comme, par exemple, des immeubles.
Ce document ne donne pas de règles applicables aux cas suivants :
- appareils d’appui soumis à des efforts de soulèvement ;
- appareils d’appui pour la fonction de déplacement spécifique des ponts mobiles (par exemple ponts bascules, ponts levants, etc.) ;
- articulations en béton ;
- patins de nivellement.
Il peut servir de guide en cas d’appareils d’appui temporaires et les principes peuvent s’appliquer au calcul et à la fabrication d’autres types d’appareils d’appui structuraux ne faisant pas partie de la présente Norme européenne.
Si des appareils d’appui constituent tout ou partie de dispositifs antisismiques, visant à modifier la réponse dynamique de la structure, l’EN 15129 est également applicable.
Le présent document sera utilisé conjointement aux autres parties pertinentes de la série prEN 1337.

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in the EN ISO 12944 series and the
following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

• ISO Online browsing platform: available at http://www.iso.org/obp
The bearings described in this part of the prEN 1337 series may be required to operate in a plane
inclined to the horizontal. Then the terms “vertical” and “horizontal” shall be interpreted appropriately.

Note 1 to entry: National regulations may distinguish between durability of corrosion protection in terms of
discolouration and blistering, etc. or the period of time until minor maintenance and period of time until major
maintenance.

4 Types of bearings
In Tables 1 to 9, common types of bearings and their load transfer and movement capabilities in the
horizontal plane are characterized by an unambiguous code, consisting of a combination of letters from
the abbreviations indicating the type of bearing, followed by a number from the abbreviations,
indicating the numbers of directions in which horizontal displacement is allowed. The latter can be
followed by a letter, which indicates whether the movement is allowed by deformation or sliding in the
bearing. The icons are meant to be used for bearing schedules in order to avoid confusion.
Due to the nature of the bearings, acting in their environment, reaction moments can occur and shall be
considered where relevant.
The designs given in the table are neither normative nor exhaustive.
The load transfer and movement possibilities of the bearings are expressed in a Cartesian coordinate
system, in which x and y define the horizontal plane and z the vertical direction. x is normally oriented
in the longitudinal direction of the superstructure and y in the transverse direction. The orientation of
the local coordinate system of the bearings may deviate from the superstructures global coordinate
system, e.g. when a guide slides in a direction other than main direction of the superstructure. In Tables
1 to 9 the load and movement direction are given for the local coordination system of the bearings. The
figures in Table 1 to Table 9 are informative only.
Figure 2 shows the relationship between the directions for loads and movements. x is usually the main
direction of displacement.
