(Main)Eurocode 6 - Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures
Eurocode 6 - Design of masonry structures - Part 1-1: General rules for reinforced and unreinforced masonry structures
(1) The basis for the design of building and civil engineering works in masonry is given in this Part 1-1 of EN 1996, which deals with unreinforced masonry, reinforced masonry and confined masonry. Principles for the design of prestressed masonry are also given. This Part 1-1 of EN 1996 is not valid for masonry elements with a plan area of less than 0,04 m2.
(2) For those types of structures not covered entirely, for new structural uses for established materials, for new materials, or where actions and other influences outside normal experience have to be resisted, the provisions given in this Part 1-1 of EN 1996 may be applicable, but may need to be supplemented.
(3) Part 1-1 of EN 1996 gives detailed rules which are mainly applicable to ordinary buildings. The applicability of these rules may be limited, for practical reasons or due to simplifications; any limits of applicability are given in the text where necessary.
(4) Part 1-1 of EN 1996 does not cover:
— resistance to fire (which is dealt with in EN 1996-1-2);
— particular aspects of special types of building (for example, dynamic effects on tall buildings);
— particular aspects of special types of civil engineering works (such as masonry bridges, dams, chimneys or liquid-retaining structures);
— particular aspects of special types of structures (such as arches or domes);
— masonry where gypsum, with or without cement, mortars are used;
— masonry where the units are not laid in a regular pattern of courses (rubble masonry);
— masonry reinforced with other materials than steel.
Eurocode 6 - Bemessung und Konstruktion von Mauerwerksbauten - Teil 1-1: Allgemeine Regeln für bewehrtes und unbewehrtes Mauerwerk
1.1 Anwendungsbereich von prEN 1996 1 1
(1) Die Grundlage für die Konstruktion und Bemessung von Gebäuden und Ingenieurbauten aus Mauerwerk ist in diesem Teil 1 1 von EN 1996 angegeben, der unbewehrtes, bewehrtes und eingefasstes Mauerwerk behandelt. Darüber hinaus sind die Grundsätze für vorgespanntes Mauerwerk angegeben. Dieser Teil 1 1 von EN 1996 gilt nicht für Mauerwerkselemente mit einer Grundrissfläche von weniger als 0,04 m2.
(2) Teil 1 1 von EN 1996 enthält ausführliche Regeln, die hauptsächlich für normale Gebäude gelten. Die Anwendbarkeit dieser Regeln kann aus praktischen Gründen oder aufgrund von Vereinfachungen begrenzt sein; alle Beschränkungen der Anwendbarkeit sind gegebenenfalls im Text angegeben.
(3) Die Ausführung wird behandelt, soweit dies notwendig ist, um die Qualität der Baustoffe und Produkte, die verwendet werden, um den erforderlichen handwerklichen Qualitätsgrad auf der Baustelle, um die Annahmen im Rahmen der Bemessungsregeln zu erfüllen, anzugeben.
(4) Für diese nicht vollständig behandelten Bauten, für neue bauliche Nutzungen bestehender Werkstoffe, für neue Werkstoffe oder wo Einwirkungen und anderen Einflüssen außerhalb der normalen Erfahrung widerstanden werden muss, können die in diesem Teil 1 1 von EN 1996 enthaltenen Bestimmungen angewandt werden, müssen aber gegebenenfalls ergänzt werden.
(5) Teil 1 1 von EN 1996 behandelt nicht:
- Feuerbeständigkeit (die in EN 1996 1 2 behandelt wird);
- besondere Aspekte bestimmter Gebäudearten (z. B. dynamische Wirkungen hoher Gebäude);
- besondere Aspekte bestimmter Arten von Ingenieurbauten (wie etwa Mauerwerkbrücken, Dämme, Schornsteine oder flüssigkeitshaltende Bauten);
- besondere Aspekte bestimmter Arten von Bauwerken (wie etwa Bögen oder Kuppeln);
- Mauerwerk, bei dem Gips mit oder ohne Zementmörtel verwendet wird;
- Mauerwerk, dessen Einheiten in einem regelmäßigen Schichtmuster verlegt werden (Bruchsteinmauern);
- mit anderen Materialien als Stahl bewehrtes Mauerwerk.
1.2 Annahmen
(1) Die Annahmen in EN 1990 gelten für prEN 1996 1 1.
Eurocode 6 : Calcul des ouvrages en maçonnerie - Partie 1-1: Règles générales pour ouvrages en maçonnerie armée et non armée
1.1 Domaine d’application du prEN 1996 1 1
(1) La présente partie 1-1 de l’EN 1996 énonce les principes de base du calcul des bâtiments et des ouvrages de génie civil en maçonnerie non armée, armée et confinée. Les principes de calcul de la maçonnerie précontrainte sont également énoncés. La présente Partie 1-1 de l’EN 1996 ne s’applique pas aux ouvrages en maçonnerie de section en plan inférieure à 0,04 m2.
(2) La Partie 1-1 de l’EN 1996 donne des règles détaillées surtout applicables aux bâtiments courants. Leur mise en application peut s’avérer limitée, pour des raisons pratiques ou du fait de simplifications ; toute restriction d’application est détaillée, le cas échéant, par le texte.
(3) L’exécution des travaux n’est traitée que dans la mesure nécessaire à la définition des qualités de matériaux de construction et de produits à mettre en œuvre, et à la définition de la qualité d’exécution sur chantier requise conformément aux hypothèses des règles de calcul.
(4) Pour ces types de structure non entièrement couverts, des nouveaux types de structure pour des matériaux traditionnels, des nouveaux matériaux ou lorsque les actions et autres influences en dehors de l’expérience courante doivent être prises en compte, les dispositions de la présente Partie 1-1 de l’EN 1996 peuvent être appliquées, mais avec la nécessité éventuelle de compléments.
(5) La Partie 1-1 de l’EN 1996 ne traite pas les sujets suivants :
- la résistance au feu (qui est traitée par l’EN 1996-1-2) ;
- les aspects particuliers de types de bâtiments spéciaux (tels que les effets dynamiques exercés sur les bâtiments élevés) ;
- les aspects particuliers de types spéciaux d’ouvrages de génie civil (tels que les ponts, barrages, cheminées ou réservoirs en maçonnerie) ;
- les aspects particuliers de types spéciaux de structure (tels que les voûtes ou les coupoles) ;
- la maçonnerie qui utilise les mortiers de plâtre avec ou sans ciment ;
- la maçonnerie pour laquelle les éléments ne sont pas posés selon un aspect régulier (maçonnerie de moellons bruts) ;
- la maçonnerie armée au moyen d’autres matériaux que l’acier.
1.2 Hypothèses
(1) Les hypothèses énoncées dans l’EN 1990 s’appliquent au prEN 1996-1-1.
