Національний додаток до EN 1996-2
Стандарт містить варіанти методик, значення та рекомендації, які на національному рівні повинні бути розроблені. Для цього у відповідну національну редакцію EN 1996-2 включають національний додаток, що визначає вживання всіх параметрів, необхідних для розрахунку конструкцій будівель і інженерно-технічних споруд, що зводяться на території конкретної країни.
Національний вибір допускається в наступних елементах стандарту EN 1996-2: — 2.3.4.2(2) — 3.5.3.1(1)
В доповнення до загальних посилань на несуперечливу додаткову інформацію конкретні посилання можуть здійснюватися через пункт: 1.1.(2)Р 2.3.1.(1) 3.4.(3) | Foreword
This EN 1996-2 has been prepared by Technical Committee CEN/TC 250 " Structural Eurocodes", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2006, and conflicting national standards shall be withdrawn at the latest by March 2010.
CEN/TC 250 is responsible for all Structural Eurocodes.
This document supersedes ENV 1996-2: 1998.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta. Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
Background of the Eurocode programme
In 1975, the Commission of the European Community decided on an action programme in the field of construction, based on Article 95 of the Treaty. The objective of the programme was the elimination of technical obstacles to trade and the harmonisation of technical specifications.
Within this action programme, the Commission took the initiative to establish a set of armonised
technical rules for the design of construction works which, in a first stage, would serve as an
alternative to the national rules in force in the Member States and, ultimately, would replace them.
In 1989, the Commission and the Member States of the EU and EFTA decided, on the basis of an agreement1) between the Commission and CEN, to transfer the preparation and the publication of the Eurocodes to the CEN through a series of Mandates, in order to provide them with a future status of European Standard (EN). This links de facto the Eurocodes with the provisions of all the Council’s Directives and/or Commission’s Decisions dealing with European standards (eg. the Council Directive 89/106/EEC on construction products — CPD — and Council Directives 93/37/EEC, 92/50/EEC and 89/440/EEC on public works and services and equivalent EFTA Directives initiated in pursuit of setting up the internal market). The Structural Eurocode programme comprises the following standards generally consisting of a number of parts: EN 1990, Eurocode: Basis of structural design
EN 1991, Eurocode 1: Actions on structures.
EN 1992, Eurocode 2: Design of concrete structures. EN 1993, Eurocode 3: Design of steel structures. EN 1994, Eurocode 4: Design of composite steel and concrete structures.
EN 1995, Eurocode 5: Design of timber structures. EN 1996, Eurocode 6: Design of masonry structures. EN 1997, Eurocode 7: Geotechnical design. EN 1998, Eurocode 8: Design of structures for earthquake resistance. EN 1999, Eurocode 9: Design of aluminium structures.
Eurocode standards recognise the responsibility of regulatory authorities in each Member State and have safeguarded their right to determine values related to regulatory safety matters at national level where these continue to vary from State to State.
