Railway applications - Track - Concrete sleepers and bearers - Part 6: Design

This document provides particular design guidance in the following areas:
-   derivation of characteristic loads and test loads;
-   calculation of characteristic and test bending moments.
The aim of this document is to give guidance for the preparation of all data to be given by the purchaser to the supplier in accordance with Parts 1 to 5 of EN 13230. It applies to gauges 1 000 mm, 1 435 mm, 1 668 mm as well as to all lengths of sleepers and bearers.
This standard gives special criteria for the design of concrete sleepers and bearers as track components. The design methods in the Eurocode do not apply to these concrete elements.
All track parameters to be taken into account for the design of sleepers and bearers are detailed in this standard. Information is given on these parameters so that they can be used as inputs for the design calculation process. It is the responsibility of the purchaser to calculate or determine all track parameters used in this standard.
This standard gives guidance for the design calculation process. It explains how experience and calculation can be combined to use design parameters.
This standard gives examples of numerical data that can be used when applying Clauses 4 to 6 according to the state of the art.

Es werden die erforderlichen Informationen zu diesen Parametern gegeben, sodass diese als Eingangswerte für das Bemessungsverfahren verwendet werden können. Es liegt in der Verantwortung des Kunden, alle in dieser Norm verwendeten Gleisparameter zu berechnen oder festzulegen.
Dieses Dokument enthält eine Anleitung für das Bemessungsverfahren. Sie legt dar, wie Betriebserfahrung und Rechenmodelle zur Festlegung von Bemessungskennwerten kombiniert werden können.
Dieses Dokument enthält Beispiele für Zahlenwerte, die bei Anwendung der Abschnitte 4 bis 6 in Übereinstimmung mit dem aktuellen Stand der Technik verwendet werden können.

Applications ferroviaires - Voie - Traverses et supports en béton - Partie 6 : Conception

Le présent document donne des recommandations de conception particulières dans les domaines suivants :
- la répartition des charges caractéristiques et des charges d'essai ;
- le calcul des moments de flexion caractéristiques et des moments de flexion d'essai.
L'objet du présent document est de formuler des recommandations pour la préparation de l'ensemble des données que l'acheteur doit remettre au fournisseur conformément aux Parties 1 à 5 de la série EN 13230. Il s'applique aux écartements de 1 000 mm, 1 435 mm et 1 668 mm, ainsi qu'à toutes les longueurs de traverses et supports.
Le présent document établit des critères spéciaux pour la conception de traverses et supports en béton en tant qu'éléments de voie. Les méthodes de conception figurant dans l'Eurocode ne s'appliquent pas à ces éléments en béton.
Tous les paramètres de voie à prendre en compte pour la conception des traverses et supports sont décrits dans le présent document. Le présent document fournit des informations concernant ces paramètres de sorte qu'ils puissent être utilisés comme données d'entrée pour le processus du calcul de conception. Il relève de la responsabilité de l'acheteur de calculer ou de déterminer tous les paramètres de voie utilisés dans le présent document.
Le présent document donne des recommandations pour le processus de calcul de conception. Elle explique comment les données empiriques et de calcul peuvent être combinées afin d'utiliser des paramètres de conception.
Le présent document donne des exemples de données numériques qui peuvent être utilisées lors de l'application des Articles 4 à 6 conformément à l'état de l'art.
