Structural bearings - Part 1: General design rules
Full scope This part of this European Standard 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 European Standard does not give rules for
- bearings subjected to uplift;
- bearings for the specific moving function of moveable bridges (for example bascule bridges, lift bridges etc);
- concrete hinges;
It may be used for guidance in the case of temporary bearings and the principles may 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.
Lager im Bauwesen - Teil 1: Allgemeine Regelungen
Dieser Teil dieser Europäischen Norm legt allgemeine Regeln für Bemessung, Herstellung, Schutz, Transport, Zwischenlagerung, Einbau und Überwachung von Lagern im Bauwesen für die Verwendung in Brücken und anderen Bauwerken, zum Beispiel Hochbauten, fest.
Diese Europäische Norm beinhaltet keine Regeln für
- Lager, die vertikalen Zugkräften ausgesetzt sind;
- Lager für die spezifische Bewegungsfunktion von beweglichen Brücken (z. B. Klappbrücken, Hubbrücken usw.);
- Betongelenke.
Sie darf als Leitlinie im Falle temporärer Lager verwendet werden und die Grundsätze dürfen auf die Bemessung und Herstellung anderer Typen von Lagern im Bauwesen, die nicht in dieser Europäischen Norm enthalten sind, angewendet werden.
Wenn Lager mit dem Ziel die dynamische Antwort des Tragwerks zu verändern als oder als Teil von Erdbebenvorrichtungen verwendet werden, gilt auch EN 15129.
ANMERKUNG Der informative Anhang H darf Hintergrundinformation geben.
