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.

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
