Eurocode 6 - Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures

Eurocode 6 applies to the design of buildings and civil engineering works, or parts thereof, in unreinforced, reinforced, prestressed and confined masonry. Eurocode 6 deals only with the requirements for resistance, serviceability and durability of structures. Other requirements, for example, concerning thermal or sound insulation, are not considered. Execution is covered to the extent that is necessary to indicate the quality of the construction materials and products that should be used and the standard of workmanship on site needed to comply with the assumptions made in the design rules. Eurocode 6 does not cover the special requirements of seismic design. Provisions related to such requirements are given in Eurocode 8 "Design of structures in seismic regions" which complements, and is consistent with, Eurocode 6. Numerical values of the actions on buildings and civil engineering works to be taken into account in the design are not given in Eurocode 6. They are provided in Eurocode 1 "Actions on structures".

Domaine d'application
   Domaine d’application de l’Eurocode 6
(1)P L’Eurocode 6 s’applique au calcul des bâtiments et des ouvrages de génie civil, ou de parties d’ouvrage, en maçonnerie non armée, armée, précontrainte ou confinée.
(2)P L’Eurocode 6 ne traite que ce qui concerne les prescriptions de résistance, de service (aptitude a l’emploi) et de durabilité des ouvrages. Les autres prescriptions, par exemple celles relatives aux isolations thermiques ou acoustiques, ne sont pas abordées.
(3)P L’exécution des travaux n’est traitée que dans la mesure nécessaire a la définition des qualités de matériaux de construction et de produits qu’il convient de mettre en ouvre, et a la définition de la qualité d’exécution sur chantier requise conformément aux hypotheses des regles de calcul.
(4)P Le présent Eurocode 6 ne traite pas des prescriptions particulieres du calcul au séisme. Les dispositions a prendre vis a vis de telles prescriptions sont données par l’Eurocode 8, qui est cohérent avec l’Eurocode 6 et le complete.
(5)P Les valeurs numériques des actions devant etre prises en compte dans le calcul des bâtiments et des ouvrages de génie civil ne sont pas données par l’Eurocode 6. Ces valeurs figurent dans l’Eurocode 1.

Evrokod 6: Projektiranje zidanih konstrukcij - 1-1. del: Splošna pravila za armirano in nearmirano zidovje

(1)P   Evrokod 6, 1-1. del daje podlago za projektiranje stavb in gradbenih inženirskih objektov iz zidovja. 1-1. del obravnava nearmirano in armirano zidovje, kjer dodana armatura izboljša duktilnost in nosilnost ali uporabnost. Podaja načela za projektiranje prednapetega in povezanega zidovja, vendar brez pravil za uporabo. Ta del ne velja za zidovje s tlorisno površino manj kot 0,04 m2.
(2)   Za tiste tipe konstrukcij, ki jih standard ne zajema v celoti, za nove vrste uporabe konstrukcij iz uveljavljenih materialov, za konstrukcije iz novih materialov oziroma za konstrukcije, ki morajo prevzeti vplive in druge posledice, za katere ni običajnih izkušenj, se načela in pravila za uporabo, navedena v tem standardu, lahko uporabljajo, vendar se po potrebi dopolnijo.
(3)   1-1. del navaja podrobna pravila, ki so v glavnem uporabna za običajne stavbe. Zaradi praktičnih razlogov ali poenostavitev je uporabnost teh pravil lahko omejena. Kakršnakoli omejitev uporabnosti je omenjena med besedilom na mestih, kjer je potrebno.
(4)P   1-1. del obravnava naslednja poglavja:
1. del: Splošno
2. del: Osnove projektiranja
3. del: Materiali
4. del: Trajnost
5. del: Analiza konstrukcije
6. del: Končno mejno stanje
7. del: Mejno stanje uporabnosti
8. del: Detajli
9. del: Izvedba
(5)P   1-1. del ne obsega:
požarne odpornosti (ki jo obravnava EN 1996-1-2);
posebnih vidikov posebnih tipov stavb (na primer dinamičnih učinkov na visoke stavbe);
posebnih vidikov posebnih tipov gradbenih inženirskih objektov (kot so zidani mostovi, pregrade, dimniki ali konstrukcije, ki zadržujejo tekočine);
posebnih vidikov posebnih tipov konstrukcije (kot so loki ali kupole);
zidovja, kjer se za zidanje uporabljajo malte z mavcem brez cementa ali z njim;
zidovja, kjer zidaki niso položeni v pravilnem razporedu v vrstah (kamnito zidovje);
zidovje, armirano z drugimi materiali kot z jeklom.

EN 1996-1-1:2005 (E) 7 Foreword This document EN 1996-1-1 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 May 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 1996-1-1:1995 and ENV 1996-1-3:1998. 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 to 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 harmonised 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.

For fifteen years, the Commission, with the help of a Steering Committee with Representatives of Member States, conducted the development of the Eurocodes programme, which led to the first generation of European codes in the 1980’s.

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 (e. g. the Council Dire
