BS EN 13230-6:2020 pdf free.Railway applications – Track 一Concrete sleepers and bearers Design
BS EN 13230-6 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 Parts1 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 document 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 thisdocument. 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 document. This document gives guidance for the design calculation process. It explains how experience and calculation can be combined to use design parameters. This document gives examples of numerical data that can be used when applying Clauses4 to 6 according to the state of the art.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13146-3, Railway applications – Track – Test methods for fastening systems – Part 3: Determination of attenuation of impact loads.The track is an assembly of transverse concrete sleepers or bearers secured to the rails by means of a fastening system and supported by ballast or other support It is characterized by the gauge of the track, the rail profile, the inclination of the rails and the spacing of the concrete sleepers and bearers. The assembly including the rail, the fastening system and concrete sleepers or bearers on ballast or other support may be considered as a beam on an elastic foundation. BS EN 13230-6 pdf download.
