Foreword
This document (EN 12794:2005) has been prepared by Technical Committee CEN/TC 229 “Precast concrete
products”, the secretariat of which is held by AFNOR.
This document was examined by and agreed with a joint working party appointed by the Liaison Group
CEN/TC229-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text or by endorsement, at the latest by August 2005, and conflicting national standards shall be withdrawn at
the latest by November 2006.
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:
prEN 1168, Precast concrete products — Hollow core slabs
EN 12794, Precast concrete products - Foundation piles
EN 12843, Precast concrete products — Masts and poles

relevant EN Eurocodes (EN 1992-1-1). 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, 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, Cyprus, Czech Republic,

4.3.3 Mechanical resistance
4.3.3.1 General
4.3.3 deals only with the nominal mechanical strength of the pile itself. The bearing capacity of the pile in its
final position on site also depends on the geotechnical considerations, which are out of the scope of this
document.
4.3.3.1 of EN 13369:2004 shall apply.
Due to the position of the reinforcement in the single bar pile and the absence of confining reinforcement in
the shaft of this type of pile, the piles in this document are divided into the classes defined in Table 3.
Table 3 — Classifications of piles
Class Pile type
1 Piles or segmental piles with distributed reinforcement and/or prestressed
reinforcement with or without an enlarged pile toe, see also Annex B
2 Piles or segmental piles reinforced with single centrally placed bars, see Annex C
4.3.3.2 Verification by calculation

4.3.3.2.1 Verification of the resistance for transportation
The characteristic concrete strength at time of transportation, as specified in 4.2.2 shall be used in verification
of the resistance according to 4.3.3.2 of EN 13369:2004 with the complementary rules given in Annex B.
4.3.3.2.2 Verification of the resistance for pile installation
The characteristic concrete strength at time of pile installation shall be used in verification of the resistance for
pile installation. 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 of this document.
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.

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.
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.
