This publication comprises the English language version of ENV 1991-3:1995, Eurocode 1 — Basis of design and actions on structures — Part 3: Traffic loads on bridges, published by the European Committee for Standardization (CEN), and the National Application Document (NAD) for use with the ENV for traffic loads on bridges located in the United Kingdom (UK).
ENV 1991-3:1995 results from the programme of work initiated by the European Commission to make available a common set of rules for the design of bridges.
An ENV is made available for provisional application, but does not have the status of a European Standard. The aim is to use the experience gained to modify the ENV so that it can be adopted as a European Standard (EN).
The values for certain parameters in the ENV Eurocode may be set by CEN members to conform to the requirements of national regulations. These parameters are designated by boxed values in the ENV. The values to be used in the UK are tabulated in this NAD.
During the ENV period, reference should be made to the supporting documents listed in this NAD.
The purpose of this NAD is to provide essential information, particularly in relation to safety, to enable the ENV to be used for bridges constructed in the UK. The NAD sections/clauses are numbered in the same way as the ENV, and this NAD takes precedence over corresponding provisions in the ENV.
Users of this document are invited to comment on its technical content, ease of use, and any ambiguities or anomalies. Comments will be taken into account when preparing the UK national response to CEN on the question of whether the ENV can be converted to an EN.
Comments should be sent in writing to BSI, 389 Chiswick High Road, London W4 4AL, quoting the document reference, the relevant clause and, if possible, a proposed revision within 2 years of the issue of this document.
For the purposes of this NAD, all references to clauses, tables, figures, and annexes are references to clauses, tables, figures, and annexes in this NAD, unless otherwise specified.
Compliance with ENV 1991-3:1995 and this NAD does not of itself confer immunity from legal obligations.
This document comprises a front cover, an inside front cover, pages i to vi, pages 1 to 44, the ENV title page, pages 2 to 130, an inside back cover and a back cover.
