Precast concrete products - Bridge elements
This European Standard applies to precast concrete structural elements produced in a factory and used in bridge construction, such as deck elements.Normal weight concrete elements are considered, both reinforced and prestressed; their use can be on road bridges, railway bridges and footbridges.
Deck elements include both single elements from which the deck may be composed (beams, slabs, ribbed or cellular elements) and elements consisting of a segment of the entire deck.
Some examples of elements dealt with are shown in Annex A.
The durability aspects are also considered.
This European Standard makes reference to precast elements produced in a factory or near the construction site in a place protected from adverse weather conditions. It is assumed that if the elements are not manufactured in a factory, the production conditions assure the same level of quality control as in a factory. It is assumed that the production place is protected from rain, sunshine and wind.
Some of the elements are also treated in other European Standards (e.g. beams, slabs). This European Standard deals with the specific aspects related to the use of these elements in bridge construction.
Foundation piles, piers, abutments, barriers, bumpers, guards, arches and" box culverts are out the scope of this European Standard.
Betonfertigteile - Fertigteile für Brücken
Diese Europäische Norm gilt für im Werk hergestellte tragende Betonfertigteile zur Verwendung im Brückenbau, zum Beispiel Bauteile für den Überbau.
Es werden sowohl Stahlbeton- als auch Spannbetonbauteile aus Normalbeton zur Verwendung bei Straßen-, Eisenbahn- und Fußgängerbrücken behandelt.
Überbau Bauteile umfassen sowohl Einzelbauteile, aus denen sich der Überbau zusammensetzen lässt (Träger, Platten, gerippte oder zellenförmige Bauteile), als auch Bauteile, die einzelne Segmente des Überbaus bilden.
Einige Beispiele für Bauteile sind in Anhang A dargestellt.
Die Dauerhaftigkeit wird ebenfalls behandelt.
Diese Europäische Norm bezieht sich auf vorgefertigte Bauteile, die im Werk oder in der Nähe des Einsatzortes an einem wettergeschützten Ort hergestellt werden. Falls die Bauteile nicht im Werk gefertigt werden, müssen die Herstellungsbedingungen dergestalt sein, dass das gleiche Maß an Güteüberwachung wie im Werk sichergestellt ist. Es wird davon ausgegangen, dass der Herstellungsort vor Regen, Sonneneinstrahlung und Wind geschützt ist.
Einige der Bauteile sind auch in weiteren Europäischen Normen behandelt (z. B. Träger, Platten). Diese Europäische Norm behandelt die besonderen Aspekte, die mit der Verwendung dieser Bauteile beim Brückenbau zusammenhängen.
Gründungspfähle, Pfeiler, Widerlager, Rückhaltesysteme, Stoßfänger, Schutzeinrichtungen und Hohlkastenelemente sind nicht Gegenstand dieser Norm.
Produits préfabriqués en béton - Eléments de ponts
La présente Norme européenne s’applique aux éléments structurels préfabriqués en béton fabriqués en usine utilisés dans la construction des ponts, par exemple éléments de tablier et arches préfabriquées.
Les éléments en béton de masse volumique normale, armés ou précontraints, sont considérés ; ils peuvent être utilisés pour des ponts routiers, des ponts-rails et des passerelles.
Les éléments de tablier comprennent à la fois les éléments simples qui composent le tablier (poutres, dalles, éléments nervurés ou cellulaires) et des éléments constitués d’un tronçon de tablier complet.

L’Annexe A illustre quelques exemples d’éléments traités.
Les aspects de durabilité sont également considérés.
La présente Norme européenne fait référence à des éléments préfabriqués produits en usine ou à proximité du chantier de construction, dans un lieu protégé des conditions météorologiques défavorables. On admet que, si les éléments ne sont pas fabriqués en usine, les conditions de fabrication garantissent le même niveau de contrôle de la qualité qu’en usine. On admet que le site de production est protégé de la pluie, du soleil et du vent.
Certains éléments sont également traités dans d’autres Normes européennes (par exemple poutres, dalles). La présente Norme européenne traite des aspects spécifiques relatifs à l’utilisation de ces éléments dans la construction de ponts.
Les pieux de fondation, les piles, les culées, les parapets, les dispositifs de retenue frontaux, les garde-corps, les arches et les cadres fermés sont hors du domaine d'application de la présente Norme européenne.
Montažni betonski izdelki - Elementi za mostove
Ta evropski standard se uporablja za montažne betonske strukturne elemente, ki so izdelani v tovarni in se uporabljajo pri gradnji mostov, kot so elementi prekladne konstrukcije. Zajeti so betonski elementi običajne teže, armirani in prednapeti; uporabljajo se lahko na cestnih mostovih, železniških mostovih in brveh. Elementi prekladne konstrukcije zajemajo posamezne elemente, iz katerih je lahko sestavljena prekladna konstrukcija (tramovi, plošče, rebrasti ali celični elementi), ter elemente iz segmenta celotne prekladne konstrukcije. !besedilo črtano. Nekateri primeri obravnavanih elementov so prikazani v dodatku A. Upoštevani so tudi vidiki trajnosti. Ta evropski standard se sklicuje na montažne elemente, izdelane v tovarni ali v bližini gradbišča na mestu, zaščitenem pred neugodnimi vremenskimi razmerami. Če elementi niso izdelani v tovarni, se predpostavlja, da pogoji proizvodnje zagotavljajo enako raven nadzora kakovosti kot v tovarni. Predpostavlja se, da je mesto proizvodnje zaščiteno pred dežjem, soncem in vetrom. Nekateri elementi so zajeti tudi v drugih evropskih standardih (npr. tramovi, plošče). Ta evropski standard obravnava specifične vidike v zvezi z uporabo teh elementov pri gradnji mostov.

The installation of some structural precast concrete products is dealt with by ENV 13670-1: Execution of concrete structures – Part 1: Common rules, which has at the moment the status of a European prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as a European Standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts: EN 1168, Precast concrete products — Hollow core slabs EN 12794, Precast concrete products — Foundation piles EN 12843, Precast concrete products — Masts and poles EN 13224, Precast concrete products — Ribbed floor elements EN 13225, Precast concrete products — Linear structural elements SIST EN 15050:2007+A1:2012

Typology A.1 Scope Some examples of elements dealt with in this European Standard are presented in this annex, even if this annex is not exhaustive. Other types of precast elements can be used in bridge construction. A.2 Decks with precast beams as main structural elements Some types of precast beams used in bridges are sketched in Figure A.1: rectangular beams (Figure A.1a); I or double T beams (Figure A.1b); TT beams (Figure A.1c); T beams with (Figure A.1d) or without base enlargement; inverted T beams (Figure A.1e and f); U beams, V beams (Figure A.1g and h).
Figure A.1 — Some examples of precast beams and related cast in situ concrete The following sub types of decks result: a) precast beams, completed by a cast in situ slab (Figure A.2); b) one or more U beams, completed by cast in situ slab (Figure A.3); c) segmental beams, completed by cast in situ slab (Figure A.4); d) precast T beams completed by cast in situ slab (Figure A.5); e) infilled precast beams (Figure A.6); f) precast box elements without topping (Figure A.7). In types from a) to c) thin floor plates are frequently used as permanent formwork for the cast in situ concrete slab (see B.6).

Decks formed by beams and slabs B.1 Scope This annex deals with decks having precast beams as the main resistant elements, i.e. types described in A.1 a), b), c) and d). B.2 Dimensions in the bearing zone The suggested minimum dimensions for the bearing zone of precast beams are shown in Figure B.1 (full depth bearings ) and in Figure B.2 (half joints). Such dimensions are to be intended as design specifications and not as acceptance tolerances. Deviations from the above values require special detailing provisions to assure safety against local spalling of concrete. Half joints (Figure B.2) can lead to durability and maintenance problems because of difficulties in inspection and in bearings replacement and should be avoided as far as possible. In case of beams to be placed with a longitudinal gradient greater than 3 %, a cavity should be provided in the underside of the beam to ensure a horizontal bearing surface at the support. In the cavity area the minimum concrete cover should still be guarantied. B.3 Transfer of prestressing 8.10.2 and 8.10.3 of EN 1992-1-1:2004 and 8.10 of EN 1992-2:2005 should apply. When the prestressing tendons are placed outside of the vertical plane of the webs, a horizontal transfer check should be made. This is particularly important for very wide elements such as box and U beams. B.4 Anchorage of the main reinforcement at supports At the end of the beams, enough support length should be provided to verify that the horizontal force, derived from the shear mechanism, is resisted by the tension chord. When the transfer of prestressing is assured by bond (pre-tensioned beams), the part of prestressing effectively anchored can be evaluated according to 8.10.2.2 and 8.10.2.3 of EN 1992-1-1:2004. The effectiveness of tendons placed at a distance from the web edge greater than the thickness of the flange should be verified case by case. If the force provided by the prestressing is insufficient, adequately anchored reinforcing steel should be added. SIST EN 15050:2007+A1:2012
