PRE-STRESSING LOSSES - TYPICAL DATA
Notes: To reduce excess friction, it may be possible to flush the tendon with water or water soluble oil.If the duct or strand has a film or rust, the ducts are full of water, the friction values can increase significantly.(1) Allow for 5% loss in effective jacking force at surface recessed stressing pans.
(*) Tendon wobble values listed are indicative only. Actual wobble is often dependent on construction technique andworkmanship.

Post-tensioning (PT) is an efficient way of reinforcing concrete while you are building often allowing the construction
of something which might otherwise have been impossible. It can also be combined with other structural materials,
such as steel and masonry structures. PT provides active reinforcement and places the concrete structure under
compression in those regions where load causes tensile stress.
Massive developments in post-tensining over the past decades means that it is now a mainstream component of the
construction industry and is applied in bridges, buildings, arenas, dams, nuclear power stations, wind farms, cryogenic
LNG tanks, silos, wastewater treatment plants, water reservoirs, marine structures, retaining walls, towers and tunnels.
Post-tensioning vs. pre-tensioning
Both post-tensioning and pre-tensioning create prestressed
concrete.
Pre-tensioned systems, however, must be fabricated in
a precast plant and are limited to straight, harped, or
circular tendons. In addition, construction of continuous
structures is very limited with this method.
Post-tensioning, on the other hand, allows almost any
shape to be constructed and is able to match nearly
any design requirement. Internal, bonded, unbonded
and external post-tensioning is usually performed on the
project site and provides superior corrosion protection
features.
Internal vs. external post-tensioning
Tendons installed in the formwork prior to pouring the
concrete are known as internal tendons. External tendons
are placed on the outer surface of concrete structures.
This type of post-tensioning allows access for maintenance
and replacement and is therefore the solution of choice
for bridge enhancements and refurbishments, it can also
be applied to many other types of structure.

Internal bonded vs. unbonded
post-tensioning
Internal bonded post-tensioning systems can
range from a single strand to multiple strands
per tendon. The strands are inserted into a
metal or plastic duct that is then embedded
in the concrete. The duct is then filled with
cementitious grout, creating a bond with the
surrounding concrete. The grout creates an
alkaline environment which ensures corrosion
protection of the prestressing steel.
Unbonded PT differs from bonded post-
tensioning in that it provides each individual
tendon with permanent freedom of movement
relative to the concrete.
Note: Unbonded systems are not typically used in Australia.
Professional installation practice
Post-tensioning and grouting operations
require the highest level of professionalism
which is exactly what the certified BBR PT
specialists and members of the BBR Network
deliver. These well-trained and experienced
staff are continuously educated through
practical and theoretical training courses to
ensure professional execution of PT works. All
Structural Systems operatives are trained under
the Post-Tensioning Institute of Australias
(PTIAs) training programmes.
Installation of the post-tensioning starts
in conjunction with the non-tensionedreinforcement and after the formwork has
been erected. The first step in the process
is to affix the anchorages and to layout the
ducting, then the high tensile steel strands are
installed. Once the concrete is poured and
has attained its transfer strength the tendon
is stressed utilising a hydraulic jack and then
locked off at the anchorage. The anchorage
maintains the applied force in the tendon and
transfers it to the surrounding concrete. The
duct is then filled with a cementitious grout or
flexible corrosion inhibitor. Grouting is carriedout carefully under controlled conditions to
ensure that the whole tendon is completely
filled. Installation can also be performed with
a fully or partially prefabricated tendon.
Key benefits of post-tensioning structures
Greater flexibility of design PT allows highly creative architectural approaches and very demanding geometry
requirements.
Increased deflection control and improved crack control virtually crack-free concrete delivers long term durability
Faster construction program early strength stressing promotes a faster cycle time, allowing the structure to progress
more rapidly. Lower construction material costs PT can decrease the size of a structural member and reduce the quantity of
concrete and steel required for the superstructure.
Reduced environmental impact less material creates fewer carbon emissions in terms of production and transportation.
Reduced construction costs a faster cycle time and decreased amount of material minimise costs.

Multi-strand post-tensioning is
predominantly used in civil structures
including bridges, silos, tanks and
off-shore structures and is also used
for transfer beams in buildings. It
is a robust and reliable bonded
prestressing system.
BBR VT Cona CMI
The BBR VT CONA CMI post-
tensioning system is a multi-strand
system for all types of internallypost-tensioned applications. The
standard tendon sizes range from 1
to 73 seven-wire prestressing strands.
Larger sizes are also possible and
CONA CMI tendons with 91 strands
have already been used. Most
commonly, 0.6-0.62 (15.2-15.7mm)
strands with a cross-sectional area of
150mm2and a characteristic tensile
strength of 1,860 MPa are used. The
use of 0.5 (12.7mm) strands with a
cross-sectional area of 100mm2and
a characteristic tensile strength of
1,860 MPa is also possible.
The system has been granted
European Technical Approval
in accordance with the testing
procedures contained within ETAG013
and is CE marked.
These tests included static tests,
fatigue test, load transfer and
cryogenic tests.
European Technical Approval
provides clear independent review,
full and complete system testing
to the highest European standard,
quality assurance, and independent
auditing of all system components.
Every product is tested to the
same standard and afterwards an
independent auditor ensures that what
is delivered and installed on site fully
complies with that which was tested.
On completion of the tests, the
approval body evaluated the testresults, drawings, specifications and
the complete system. The package
was then circulated to all member
states of the EU for ratification.
Copies of the BBR VT European
Approval documents are available for
download from www.bbrnetwork.com.
The BBR VT CONA CMI system
has significant advantages over the
previous BBR Cona Multi system
as well as significant competitive
advantage over other ETAG approved
systems. These advantages include:
Less space is required in the
anchor zone which results in lessconcrete, slimmer structures and
less eccentricity in the anchors.
Significantly lower concrete
strength prior to stressing
resulting in shorter construction
cycles.
Less reinforcement in the
anchorage zone resulting in time
and cost savings.

Anchorage configuration
The main components in the anchor
zone of the CONA CMI system
are the wedges, anchor head,
trumplate/square plate and trumpet.
In the anchorage zone, the duct is
connected to the trumpet and the
strand bundle is spread out towards
the anchor head, where each strand
is individually locked with BBR
wedges.
For the load transfer to the
concrete, the CONA CMI BT (bearing
trumplate) can be used for tendon
sizes with 02 to 61 strands and the
CONA CMI SP (square plate) can be
used for 01 to 73 strands.
The CONA CMI BT (bearing
trumplate) system makes use of an
advanced and proprietary three plane
load transfer allowing for very small
centre and edge distances at the
anchorages, as well as application of
the full post-tensioning load at very
low concrete strengths. The CONA
CMI SP (square plate) is a system
with a single plane load transfer tothe concrete.
Technical data on the BBRVT CONA
CMI SP system can be found on
pages 24 to 27.
The stressing and fixed
anchorages
The BBR VT CONA CMI anchorages
are available in two types, theseare Type S stressing / active
anchorages and Type F fixed /
passive anchorages. The anchor
heads of the stressing and fixed
anchorages are secured by special
wedge retaining measures and
are protected by a cap during
concreting. For re-stressable and
exchangeable tendons, excess strand
length is required at the anchorage.
The extent of the excess strand
length depends on the jack usedfor re-stressing or releasing and the
strand protruding beyond the anchor
head requires permanent corrosion
protection and an adequate cap.

Fixed, stressable and movable
couplers
CONA CMI tendons can be coupled
using proprietary Type K overlap
coupler for tendons ranging from
2 to 31 strands (larger sizes on
request) or Type H sleeve coupler
for 1 to 73 strands. Both coupler
types can serve as a stressing /
active anchorage coupler (Type S)
or fixed / passive anchorage coupler
(Type F) bearing against the load
transfer unit or as movable couplers
(Type B) along the length of the
tendon.
In the first stage of construction,
the tendon is installed, stressed and
anchored in the coupler which is
placed in the section joint between
the first and second stage. Next,
the second stage tendon is put in
place and coupling is achieved by
pushing the strands into the already
tensioned Type K anchor head or
by coupling the Type H anchors
heads with a Type H sleeve. In
some countries, it is not permitted
for one section joint to have only
couplers. In this situation, it is
mandatory that at least 30% of
all tendons must be continuous in
order to obtain an even distribution
of the prestressing force in the
structure.
The movable coupler serves to
lengthen unstressed tendons and the
tendon elongation during stressing
is ensured by a cylindrical sheathing
box appropriate for the expected
elongation at the location of the
coupler. Movable couplers may be
used to couple continuity tendons at
the construction joint.
Corrosion protection
The strand bundle is enclosed in
a corrugated round steel or plastic
duct. For special applications, suchas loop tendons smooth round
steel or plastic ducts can be used.
The use of flat steel or plastic
ducts is also possible for smaller
tendon sizes. The filling of the
tendons in bonded applications is
completed using a high performance
grout. For unbonded applications,
the duct can be injected with
grease / wax. The CONA CMI
post-tensioning kits can also be
executed as fully electrically isolatedtendons to provide the highest
possible level of corrosion protection
and inspectability.
(*) Other prestressing strands approved at the place of use, such as strands having a cross-sectional area of 140mm2or 93mm2respectively and / ora characteristic tensile strength lower than 1,860 MPa can be used with the same anchorage components.

Dead end anchorages bulb type and swage type
Tendon curvature
A straight portion L adjacent to the anchorage must be observed to limit the screw pull of the strand bundle against
the anchorage. Reduction may be allowed in certain specific instances.
Tendon properties
Notes: Duct sizes are indicative, use larger duct sizes for long tendons or aggressive profiles. Duct couplers are overall +10mm larger than duct ID.
Notes: Swage type dead ends recommended for
1906 tendons and larger. Local zone and several zone anchoragereinforcement is normally required for all unittypes and details are usually determined bythe designer to suit the specific application.
