This document was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229 - CEN TC 250, particularly for its compatibility with structural Eurocodes. This document 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of an identical text or by endorsement, at the latest by November 2007 and conflicting national standards shall be withdrawn at the latest by November 2007. This document includes Amendment 1, approved by CEN on 2007-04-06. This document supersedes EN 12794:2005. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ". 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 Construction Products Directives (89/106/EEC). 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 an European prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as an 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 13747, Precast concrete products — Floor plates for floor systems prEN 15037-1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams prEN 15037-2, Precast concrete products — Beam-and-block floor systems — Part 2: Blocks EN 13224, Precast concrete products — Ribbed floor elements EN 13225, Precast concrete products — Linear structural elements

They shall be cast in, in such a way, that their position can be inspected during production and on the finished product. The quality of the further structural parts, e.g. locking parts, necessary to complete the actual joining of the pile segments at the site of installation, shall be the pile producer’s responsibility. The site assembly of pile joints is not covered by this document. Pile joints shall locate and maintain a coaxial connection between pile segments. The faces of the pile components shall be perpendicular to the axis of the pile segments within the following tolerances: centres of cast in components shall not deviate more than 10 mm from the central axis of the pile/pile segment; angular deviation of the faces of the pile components shall not exceed an inclination of 1:150.

The verification of the resistance for pile installation shall conform to relevant documents or other provisions valid in the place of use taking in consideration the specific geographical conditions which refer specifically to the installation of the precast concrete foundation piles. !NOTE 1
Provisions for pile installation may give higher minimum requirements for the concrete class and reinforcement than specified in 4.2, Annex B (class 1) and Annex C (class 2) of this European Standard." NOTE 2 Guidance for the execution of pile foundations is given in EN 12699. NOTE 3 Provisions regarding the soil conditions in the place of use can be given for pile type – Class 2 – as specified in Annex C. 4.3.3.2.3 Resistance to design loads Resistance to design loads at the critical section of the pile shaft shall (e.g. near the joint) be verified by the calculation in accordance with 4.3.3.2 of EN 13369:2004. NOTE The calculated resistance of the pile cross section with respect to the axial force will be at least equal to the geotechnical load bearing capacity of the installed foundation pile.

Impact load test with 500 impact blows having stress level 17 N/mm2. 1 !deleted text" 1 Stress level means: compressive stresses around the pile joint caused by impact blows. 2 Pile joint class (i.e. the dynamic stress level during Impact load test) is chosen according to national provisions to correspond the target geotechnical capacity of the segmental pile. NOTE Pile joints with better class than specified in the piling specification may be used. For the pile joints connected with the pile segment, the pile joint class, gap width, calculated characteristic static bearing capacity (i.e. compression, tension and bending capacity) shall be declared as well as the flexural stiffness at the level of 0.75 x calculated ultimate bending moment. Robustness and rigidity of pile joints shall be verified by impact loading testing followed by subsequent bending testing in conformity with the procedures and methods given in Annex A. Class A, B and C: The ultimate bearing capacity (compression, tension and bending) of the pile joint shall be calculated taking in account the design strengths of materials. Provided that the impact load test and subsequent bending test can verify the static calculations, then the ultimate bearing capacity of the joint is identical to the static calculated bearing capacity. !To verify the test results, the actual strength of the applied materials, the effect of short term loading and γm = 1 shall be taken into account when calculating the shaft and the joint capacity." Robustness and rigidity may be deemed adequate if the pile joint performs satisfactorily in the test indicated in Annex A. Class D: The ultimate bearing capacity (compression) of the pile joint shall be calculated taking in account the design strengths of materials. Provided that the impact load test can verify the static calculations, then the ultimate bearing capacity of the joint is identical to the static calculated bearing capacity. Robustness and rigidity may be deemed adequate if the pile joint performs satisfactorily in the test indicated in Annex A. In this case the subsequent bending test is not performed.
