Holder of the three European Technical Approvals is :
SOLETANCHE FREYSSINET
1bis, rue du petit Clamart
F-78140 VELIZY
The present document contains all the technical data and content of the three above
mentioned documents : It replaces last version of ETA-06/0226,
It cancels and supersedes ETA-11/0172 and ETA-10/0326.
B.1 DEFINITION OF PRODUCTS AND INTENDED USE
B.1.1 Definition of Products
The Freyssinet prestressing kit is a post-tensioning kit designed for both internal and external
prestressing. A prestressing cable consists of a bundle of 7-wire strands in accordance with
section G.1 and is referred to as the ‘tensile element’. When fitted with its anchorages, the
prestressing tendon is referred to as the ‘prestressing unit’.
The tensile element is housed in a duct in accordance with section G.2.
In the case of unbonded internal prestressing, however, monostrands (strands with individual
protection by grease or wax and plastic sheath) may be used without any duct, the strands
being placed in the structure according to the design requirement.
The set of anchorages available allows using prestressing units up to 55 strands.
Prestressing strands can be made in accordance with European and national provisions.
The prestressing tensile elements consist of:
12,5 mm or 12,9 mm nominal diameter strands, with a nominal tensile strength of
1770 MPa or 1860 MPa, coded respectively Y1770 (or Y1860) S7 12,5 (or 12,9) in
prEN 10138-3 and designated T13, T13S or simply T13 in the present document,
15,3 mm or 15,7 mm nominal diameter strands, with a nominal tensile strength
1770 MPa or 1860 MPa, coded respectively Y1770 (or Y1860) S7 15,3 (or 15,7) in
prEN 10138-3 and designated T15, T15S or simply T15 in the present document.
Freyssinet stressing anchorages anchor each strand individually by means of a conical wedge
inserted in a conical hole of anchorage block. The diameter of the internal thread of the
Freyssinet anchor wedge depends on the strand nominal diameter, T13 or T15 (drawings 1, 2
and 3).
European Technical Approval n° 06/0226 Page 8 of 56 _________________________________________________________________________________
Version of 28th June 2013
B.1.1.1 Stressing anchorages
Anchorages are said to be the stressing type (and are coded ‘A’ for ‘active’) when they are the
anchorages at the end of tensile elements where the tensioning operation takes place. A
stressing anchorage consists of an anchorage head, i.e. a steel block or a casting with holes to
receive anchorage wedges. The anchorage head bears on a load spreading plate, except for
models F and X where the load spreading plate is part of the anchorage block. This load
spreading plate is:
either a casting known as a ‘trumplate’, which is cast into the concrete of the structure,
or a bearing plate of dimensions to suit the load-bearing capacity of the structure.
Different active anchorage models are available, to meet specific construction needs.
Structural anchorages model C
Prestressing anchorages model C are generally used for civil engineering prestressed
structures. They consist of a circular steel anchor head bearing on a cast-iron trumplate with
one or several intermediate spreading rings. They cover a range between 3 and 55 strands T13
or T15 (drawings 11 to 19).
Slab anchorages model F
Prestressing anchorages model F are generally used for prestressing thin elements (e.g.
concrete floor slabs and walls) and consist of a one-piece casting which combines the
anchorage block and the trumplate. It is available for prestressing units with 1, 3 or 4 strands
T13 or T15 (drawings 24 to 28).
Slab anchorages model B
Prestressing anchorages of the Freyssinet B system are generally used in prestressed thin
elements of the concrete structures. They are composed of cast-iron anchorage block and
trumplate. The model B cover a range between 3 and 5 strands T15 and T13 (see drawings 29
to 31).
Hoop anchorages model X
The Freyssinet hoop anchorage consists of a casting bearing against the circular structure
which serves as anchorage to the two ends of one or two hoops:
The 1 X anchorage is used to make one prestressing hoop, with radius of up to 27,5 m
(drawing 32),
The 2 X anchorage is used to anchor two hoops, each wrapped once or twice around
the structure, with radius of up to 5,5 m (drawing 33).
B.1.1.2 Passive anchorages
When anchorages are said ‘external passive’ they will not allow fitting of a tensioning jack
but are nevertheless accessible during the tensioning operation. This kind of anchorage is
made out of stressing anchorages in which the wedges have been pre-blocked, without
protruding tendon length for tensioning. They can be inspected during tensioning. The
Freyssinet denomination for these types is identical to that of stressing anchorages.
European Technical Approval n° 06/0226 Page 9 of 56 _________________________________________________________________________________
Version of 28th June 2013
Anchorages are said embedded or internally fixed when incorporated in concrete of structure.
These NB designated anchorages use swages to ensure fixing of strand ends (drawings 4 to 6)
on a model C anchor head fitted with cylindrical holes and seated on a trumplate. They can be
used for units ranging from 3 to 55 strands T13 or T15 (drawing 23).
B.1.1.3 Fixed Couplers CI
Couplers connect two tensile elements that are tensioned one after the other in two separate
concreting phases
Monostrand fixed coupler
It consists of individual type P strand connectors (see paragraph B.1.1.4 below) connecting
each strand of the primary tendon to its counterpart in the secondary tendon (drawing 20). It is
used with all active stressing anchorages for prestressing units with 1 to 37 strands T13 or
T15.
The reinforcement in the deviation zone has to be calculated by the project designer.
Multistrand fixed couplers
Multistrand fixed couplers (drawing 21) connect two tensile elements that are tensioned one
after the other in two separate concreting phases.
They are made of machined steel with two series of conical holes bored, each series counting
at least as many holes as there are strands in the prestressing tendon.
Units with 3, 4, 7, 9, 12, 13, 15, 19, 22, 25, 27, 31 and 37 conical holes are available in the
range.
The holes of the first series are positioned in the central part of the coupler, according the
same pattern as for the C anchorages of the basic kit.
The holes of the second series are bored on the opposite side of the coupler, according a
circular pattern. For unit 31 and 37, these holes are positioned on two concentric circles.
B.1.1.4 Movable couplers CM
Movable couplers CM connect two tensile elements which are tensioned simultaneously in a
single operation. Strands are connected together with a type P individual strand connector;
strand connector positions are offset in the case of multistrand units.
The connector consists of a cast-iron body to receive two anchorage wedges and serves to
connect two sections of a tensile element. Two models are available:
strand connector P 13 is used with T13 and T13S strands (drawing 8),
strand connector P 15 is used with T15 and T15S strands (drawing 7).
Movable couplers are used for prestressing units with 1 to 37 strands T13 or T15
(drawing 22).
The length of the coupler reservation is obtained by the formula L = M + U, where U is the
connector displacement including provision for stressing tolerance according to national
regulations and M is a fixed dimension depending on the tendon type including necessary
installation tolerance given in the table of relevant drawings.

B.1.1.6 Other Components
Prestressing units of Freyssinet kit require different components, some of them being
common to several models.
- Ducts, used to isolate, guide and protect tensile elements (see section G.2). They can
consist of steel or plastic corrugated sheath or steel or plastic tubes or pipes.
- Connecting accessories may be improved by plastic adhesives, heat-shrink sleeves or
mastic.
- Injection materials for anchorages and ducts, such as cement grout, grease and wax.
- Tubes or specific elements for deviation of external cables at given locations in the
structure. These deviators are generally made out of steel plain pipes. The specific
elements may include reservations inside the concrete reinforcement or construction steel
saddles to obtain the cable deviator.
- Bursting steel reinforcement, for the concrete confinement at anchorages and deviators, to
complete the general concrete structural reinforcement and ensure prestressing force
transfer.
- Specific accessories to facilitate cable placing and stressing, tendon grouting, de-
tensioning and replacement of tendon, such as vents, duct drainage, tendon supports,
European Technical Approval n° 06/0226 Page 11 of 56 _________________________________________________________________________________

Each main component has a prescribed inspection plan, established by Freyssinet and applied
by its manufacturers. Production control methods are defined in the Freyssinet Quality
Assurance Plan PAQ ATE PRE.
At least once a year, each component producer is audited by the kit manufacturer. The results
of the audit shall be made available to the certifying body.
B.3.2.2 Tasks of the Certification Body
Methods of surveillance for production control are defined in the Quality Assurance Plan
established and updated by Freyssinet, in conformity with paragraph 8.2.2 of ETAG 013.
The main production centre is checked at least once a year by the Certification Body. Each
component producer is checked at least once every five years by the Certification Body.
The Certification Body checks inspection results, control tests as well as results of production
control results and establishes the conformity to the ETA.
Corrective measures are taken by the Manufacturer when defects have been met. These
measures are:
corrective intervention, following the notification of the Certification Body,
control strengthening and higher test frequency,
setting-up of modifications.
During continuous surveillance auditing, the Certification Body takes samples to test in
independent laboratories. Samples are taken according to the requirements of the table
attached in the chapter D of this ETA.
During the certificate validity the ETA holder supplies once a year to the Certification Body
anchorages and strands necessary for a test series according to Annex E of ETAG 013 and
sends them to the laboratory designated by the Certification Body.
These well-identified parts and tensile elements are from the same construction site. If
possible, construction sites are chosen in such a way that the tensile element manufacturer
will be different from year to year.
B.3.2.3 CE Marking
The CE marking must comply with the European Council Directive 89/106/CEE, and to the
EC guideline "D" related to the marking. The delivery bill accompagnying the PT kit
components shall bear the conformity CE marking symbol and the following mentions :
1. Name and address of kit manufacturer,
2. Last two digits of the year during which the marking has been made,
3. Number of conformity certificate,
