EN 15050:2007 (E) 4 Foreword This document (EN 15050:2007) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR and was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229-CEN/TC250, particularly for its compatibility with structural Eurocodes. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by February 2009. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369: Common rules for precast products, from which also the relevant requirements of the EN 206-1: Concrete — Part 1: Specification, performances, production and conformity are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects.
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 EN 13693, Precast concrete products — Special roof elements EN 13747, Precast concrete products — Floor plates for floor systems EN 13978, Precast concrete products — Precast concrete garages EN 14843, Precast concrete products — Stairs EN 14844, Precast concrete products — Box culverts EN 14991, Precast concrete products — Foundation elements EN 14992, Precast concrete products — Wall elements

Where, in default of applicability conditions of EN Eurocodes to the works of destination, design Provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: 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.



EN 15050:2007 (E) 6 Introduction The evaluation of conformity given in this European Standard refers to the completed precast concrete elements for bridges that are supplied to the market and covers all the production operations carried out in the factory. For design rules and resistance to fire reference is made to EN 1992-1-1 and EN 1992-1-2. Additional complementary rules are provided where necessary. In 4.3.3 and 4.3.4 this European Standard includes specific provisions resulting from the application of EN 1992-1-1, EN 1998-1, EN 1992-1-2 and EN 1992-2 rules made specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1, EN 1992-1-2, and EN 1992-2.



EN 15050:2007 (E) 7 1 Scope This European Standard applies to precast concrete structural elements produced in a factory and used in bridge construction, for example deck elements, abutments, elements for piers and precast arches. 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. The elements for abutments are precast elements able to support vertical and horizontal actions applied by the deck and the earth pressure due to the filling material. The pier elements can consist of a segment of the pier or, for small heights, the entire pier. 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, barriers, bumpers, guards and box culverts are out the scope of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 15050:2007 (E) 8 3 Terms and definitions For the purposes of this document, the following terms and definitions given in EN 1992-1-1:2004 and EN 13369:2004 and the following apply. 3.1 bridge civil engineering construction works mainly intended to carry loads related to communication over a natural obstacle or a communication line NOTE This includes all types of bridges, especially road bridges, footbridges, railway bridges etc. 3.2 abutment end support of a bridge NOTE Rigid abutments and flexible abutments should be distinguished where relevant. 3.3 pier intermediate support of a bridge, situated under the deck 3.4 bearing device structural device located between the deck and an abutment or pier of the bridge and transferring loads from the deck to the abutment or pier 3.5 prestress permanent effect due to controlled forces and/or controlled deformations imposed on a structure NOTE Various types of prestress shall be distinguished from each other as relevant (for example pre-tensioning, post-tensioning by tendons, prestress by imposed deformation at supports). 3.6 headroom free height available for traffic 3.7 continuous bridge bridge with continuous deck surface through adjacent intermediate spans, with or without structural continuity 3.8 floor plate reinforced or prestressed concrete plate used as permanent formwork for cast-in-situ concrete with which it generally contributes structurally when the cast-in-situ concrete has hardened to form a composite slab 3.9 integral bridge bridge with no expansions joints neither between adjacent intermediate spans nor between end spans and abutments 3.10 diaphragm transverse deck stiffener (precast or cast in-situ)



EN 15050:2007 (E) 9 3.11 crosshead transverse support beam at an intermediate or end deck support 3.12 sagging moment bending moment inducing tension in the bottom fibres (positive moment) 3.13 hogging moment bending moment inducing tension in the top fibres (negative moment) 3.14 skew angle angle between the crosshead and a line perpendicular to the longitudinal axis of the bridge 4 Requirements 4.1 Material requirements EN 13369:2004, 4.1 shall apply. For indented bar and wire refer to EN 10080. In case that the prestressing steel axis is deviated, deflectors shall not engrave the prestressing steel nor cause important voids in the concrete element. The strength of the deviated prestressing steel shall be not less than 95 % of the straight one. 4.2 Production requirements 4.2.1 General The production of precast elements for bridges shall comply with the requirements in EN 13369:2004, 4.2 and with the following complementary subclause. For bridge elements other values than given in EN 13369:2004, 4.2.1.3 may be given following the requirements of their destination as indicated in the design documentation. 4.2.3.2 Application of prestressing 4.2.3.2.1General If the transfer of prestress anchored by bond (pre-tensioning) is not gradual, the slippage, which is the shortening of the tendon after transfer of the prestressing force, shall be checked according to Annex J. The measured values have to be in accordance with the limit values indicated in EN 13369:2004, 4.2.3.2.4. The measured slippage shall not be used to determine the transmission length. The check does not apply to debonded strands.



EN 15050:2007 (E) 10 4.2.3.3 End protection of debonded strands When the ends of debonded strands are protected, a soft material should be used so that as the beam continues to creep, the unbonded strand length which does not shorten with the beam does not destroy the end protection. This soft cover (e.g. a bead of foam) should also be used even when the strand is to be cast into a diaphragm. 4.3 Finished product requirements 4.3.1 Geometrical properties 4.3.1.1 Production tolerances The permitted deviations of 4.3.1.1 of EN 13369:2004 shall be considered for geometrical dimensions. For beams and box beams the complementary indications of Table 1 apply. The permitted deviations indicated in the Table 1 are the limiting values of the difference between actual values (measured as described in Clause 5) and theoretical values shown on the design drawings; the permitted deviation of any dimension shall be not less than 5 mm. Table 1 — Permitted deviations (see Figure 1) Dimension Permitted deviation Vertical skewness (v1, see Figure 1b) ± 0,015 h Horizontal skewness (v2, see Figure 1c) ± 0,02 b or ± 0,02 a (which is relevant) Verticality (g, see Figure 1d) ± 0,015 h Lateral deviation (with reference to theoretical axis) ± L/500 ± 50 % of the declared value or L/800 Camber or sag (with reference to the declared value evaluated taking into account the age and the load history of the element)
(which is greater)

EN 15050:2007 (E) 12 4.3.1.2 Permitted deviations of inserts and holes The permitted deviations in positions of inserts and holes (and of minor details not involving the structural behaviour) shall be specified in the manufacturer drawings. Lacking different specifications, a permitted deviation of ± 30 mm shall be assumed for a single insert or hole. For the mutual position within a group, the permitted deviation shall be assumed ± 5 mm. 4.3.1.3 Minimum dimensions The minimum dimensions of structural members are defined by the structural calculations, by the provision of the values of cover required by EN 1992-1-1, EN 1992-2 and by this European Standard. NOTE Greater dimensions can be indicated by the client or by the National Rules having regard to climate and environment. 4.3.2 Surface characteristics The external aspect of each precast element shall be inspected at the time of demoulding in order to detect visible defects, such as voids, surface defects, cracking etc., with reference to J.4 of EN 13369:2004. Defects of limited importance can be treated after transfer of prestress, preferably using non-shrinkage mortar or prestress, after a surface cleaning of the defective area. Cracks perpendicular or almost perpendicular to the direction of prestress, detected before transfer and not exceeding 0,2 mm in width, shall not be taken into account. Recesses deeper than 8 mm (5 mm for external surfaces of edge beams or upper surfaces of bottom flanges) should be filled using an appropriate mortar having strengt
