CEN/TS 1992-4-1:2009
(Main)Design of fastenings for use in concrete - Part 4-1: General
Design of fastenings for use in concrete - Part 4-1: General
1.1 General
1.1.1 This CEN/TS provides a design method for fasteners for structural purposes, which are used to transmit actions to the concrete.
Inserts embedded in precast concrete elements during production, under FPC conditions and with the due reinforcement, intended for use only during transient situations for lifting and handling, are covered by the CEN/TR “Design and Use of Inserts for Lifting and Handling Precast Concrete Elements”, by CEN TC 229.
1.1.2 This CEN/TS is intended for applications in which the failure of fastenings will:
1) result in collapse or partial collapse of the structure, or
2) cause risk to human life, or
3) lead to significant economic loss.
1.1.3 The support of the fixture may be either statically determinate or statically indeterminate, defined as multiple anchor use in some European Technical Approvals (ETAs). Each support may consist of one fastener or a group of fasteners.
1.1.4 This CEN/TS is valid for applications which fall within the scope of the series EN 1992. In applications where special considerations apply, e.g. nuclear power plants or civil defence structures, modifications may be necessary.
1.1.5 This CEN/TS does not cover the design of the fixture. The design of the fixture shall be carried out to comply with the appropriate Standards. Requirements for stiffness and ductility of the fixture are given in clauses 5 and 8.
1.2 Type of fasteners and fastening groups
1.2.1 This CEN/TS applies to:
a) cast-in fasteners such as headed fasteners, anchor channels with rigid connection between fastener and channel;
b) post-installed anchors such as expansion anchors, undercut anchors, concrete screws, bonded anchors, bonded expansion anchors and bonded undercut anchors.
For other types of fasteners modifications of the design provisions may be necessary.

Bemessung der Verankerung von Befestigungen in Beton - Teil 4-1: Allgemeines
Conception-calcul des éléments de fixation pour béton - Partie 4-1: Généralités
1.1 Généralités
1.1.1 Le présent CEN/TS fournit une méthode de conception-calcul pour les éléments de fixation utilisés à
des fins structurelles, qui servent à transmettre des actions au béton.
Les inserts intégrés dans des éléments de béton préfabriqués au cours de la production, dans les conditions
de contrôle de production en usine (CPU) et avec le renforcement conséquent, destinés a servir uniquement
lors de situations transitoires de levage et manipulation, sont abordés par le CEN/TR « Conception-calcul et
utilisation d'inserts pour le levage et la manutention du béton préfabriqué », développé par le CEN/TC 229.
1.1.2 Le présent CEN/TS est destinée aux applications dans lesquelles la défaillance des éléments de
fixation :
1) produira un effondrement total ou partiel de la structure, ou
2) entraînera des risques pour la vie humaine, ou
3) conduira à des pertes économiques significatives.
1.1.3 L'élément à fixer peut être soit isostatique, soit hyperstatique, ou défini comme une utilisation
d’ancrage multiple dans certains Agréments Techniques Européens (ATE). Chaque support peut se
composer d’un élément de fixation ou d’un groupe d’éléments de fixation.
1.1.4 Le présent CEN/TS est valable pour les applications appartenant au domaine d’application de la
série EN 1992. Dans les applications auxquelles des considérations particulières s’appliquent, par exemple
les structures de centrale nucléaire ou de défense civile, des modifications peuvent être nécessaires.
1.1.5 Le présent CEN/TS n'aborde pas la conception-calcul de la platine de fixation. Il convient que cette
conception-calcul soit effectuée dans le respect des normes appropriées. Les exigences de rigidité et ductilité
de l'élément à fixer sont données dans les Articles 5 et 8.

Partie 4-1: Généralités Allgemeines
This Technical Specification (CEN/TS) was approved by CEN on 20 October 2008 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
