Falsework - Performance requirements and general design

This European Standard specifies performance requirements and limit state design methods for two design classes of falsework.
It sets out the rules that have to be taken into account to produce a safe falsework structure.
It also provides information where falsework is required to support a "permanent structure", or where the design or supply of falsework has to be commissioned.
This European Standard also gives information on foundations.
This European Standard does not specify requirements for formwork, although formwork may be a part of the falsework construction. Nor does it provide information on access and working scaffolds, which is given in EN 12811-1.
This European Standard does not provide information about site activities. It does not provide information about the use of some standardized products, including timber formwork beams conforming to EN 13377 and props conforming to EN 1065.

Traggerüste - Anforderungen, Entwurf und Bemessung

Diese Europäische Norm legt Anforderungen und Verfahren für die Bemessung von Traggerüsten im Grenz¬zustand der Tragfähigkeit für zwei Bemessungsklassen fest.
Sie gibt die Regeln an, die für den Aufbau und die Verwendung von Traggerüsten zu beachten sind.
Sie gibt weiterhin Angaben für den Fall, dass Traggerüste zur temporären Unterstützung von „bestehenden Bauwerken/Bauteilen benötigt werden.
Diese Europäische Norm enthält auch Angaben zu Gründungen.
Die vorliegende Europäische Norm legt keine spezifischen Anforderungen an Schalungen fest, obwohl diese Teil der Trag¬gerüstkonstruktion sein können. Sie formuliert ebenfalls keine Angaben zum Zugang und zu Arbeitsgerüsten; die entsprechenden Angaben sind in EN 12811-1 zu finden.
Diese Europäische Norm enthält keine Angaben zu Arbeiten auf der Baustelle. Sie macht keine Angaben zur Verwendung genormter Produkte auf der Baustelle, einschließlich Schalungsträger aus Holz nach EN 13377 und Baustützen aus Stahl mit Ausziehvorrichtung nach EN 1065.

Etaiements - Exigences de performance et méthodes de conception et calculs

La présente Norme européenne spécifie les exigences de performance et les méthodes de conception et calcul aux états limites pour trois classes d'étaiement.
Elle définit les règles que doit respecter le concepteur pour prendre en compte la réalisation d'une structure d'étaiement sûre.
Elle donne également des informations lorsque l'étaiement est requis pour supporter une « structure permanente », ou lorsque le calcul ou la livraison de l'étaiement doit être commissionné(e).
La présente Norme européenne donne également des informations sur les fondations.
La présente Norme européenne ne spécifie pas les exigences relatives aux coffrages, bien que ces derniers puissent faire partie d'une construction d'étaiement. Elle ne fournit pas non plus d'informations sur les tours d’accès et les parties constituées d’échafaudages de travail, qui sont spécifiées dans l’EN 12811-1.
La présente Norme européenne ne donne pas d'informations sur les activités sur site. Elle ne fournit pas d'informations sur l'utilisation de certains produits normalisés, comprenant notamment les poutrelles de coffrage en bois conformes à l'EN 13377 et les étais conformes à l'EN 1065.

Introduction Most falsework is used:  to carry the loads due to freshly poured concrete for permanent structures until these structures have reached a sufficient load bearing capacity;  to absorb the loads from structural members, plant and equipment which arise during the erection, maintenance, alteration or removal of buildings or other structures;  additionally, to provide support for the temporary storage of building materials, structural members and equipment. This European Standard gives performance requirements for specifying and using falsework and gives methods to design falsework to meet those requirements. Clause 9 provides design methods. It also gives simplified design methods for falsework made of tubes and fittings. The information on structural design is supplementary to the relevant Structural Eurocodes. The standard describes different design classes. This allows the designer to choose between more or less complex design methods, while achieving the same level of structural safety. Provision for specific safety matters is dealt with in EN 12811-1 and other documents. SIST EN 12812:2008

NOTE 1 A bow imperfection can occur both in an individual member and in the complete tower or modular beam assembly. It arises because the member is not straight, is manufactured not straight or members are assembled out of alignment. NOTE 2 These are the values for design purposes and may be more than the erection tolerance. 3.8 node theoretical intersection point of members SIST EN 12812:2008

4 Design classes 4.1 General The design shall be in accordance with one of the classes: A or B. Class B has two subclasses, B1 and B2, see 4.3 where the designer has to decide which subclass shall be applied. 4.2 Design class A NOTE A Class A falsework is one which follows established good practice which may be deemed to satisfy the design requirements. Class A covers falsework for simple constructions such as in situ slabs and beams. Class A shall only be adopted where: a) slabs have a c
