The inventor of the multistrand stay cable

A parallel strand system: robust and flexible
Freyssinet invented the multistrand parallel system in 1976. The Freyssinet HD stay cable
is based on each strand being completely independent.
This principle has many advantages, including:
• installation and tensioning of each strand individually;
• individual protection against corrosion;
• individual removal and replacement if necessary.
The standard range of HD stay cables varies from 1 to 169 strands. However, there is no
limit to the capacity or the length of stay cables. The largest stay cables yet installed were
for the Collserola telecommunications tower in Spain (205-strands) and the longest are
the stabilization stay cables for Ting Kau bridge in Hong Kong (465 m long).

The Freyssinet monostrand
A galvanised strand with a semi-bonded sheath
The tension element of the Freyssinet HD stay cable consists of a group of parallel individually protected T15.7 strands named “Freyssinet monostrand”.
This patented stay cable strand has excellent durability and provides perfect protection
against corrosion due to two complementary nested barriers formed by galvanisation
and a semi-bonded individual HDPE sheath extruded onto the strand after the interstices
have been filled with a specifically developed wax.
The bundle of Freyssinet monostrands is usually contained in an HDPE (High Density
Polyethylene) co-extruded outer pipe specially designed to satisfy stay cable needs and
to give excellent durability.

The Freyssinet anchorage
Bending filtration, high fatigue and corrosion resistance
The Freyssinet HD anchor is the most compact stay cable system. It performs all functions
required for a stay cable:
• protection against corrosion at unsheathed ends of the strands using a patented stuffing box provided with the latest developments in waterproofing;
• resistance to axial fatigue, largely due to the Freyssinet wedges specially
designed to resist 300 MPa stress amplitude at 45% of ultimate strength
for 2 million cycles;
• resistance to bending fatigue using a “filtering guide/stuffing box”
device capable of filtering radial forces;
• very easy individual installation and adjustment of strand forces. This particular
arrangement also enables monitoring of cables by replacing a test strand
at regular intervals.

It is recommended that each stay cable should have a fixed anchor at
one end and an adjustable anchor at the other.
Fixed and adjustable anchors can be installed in the tower or in the
deck indifferently and may or may not be the stressing end.
Anchors are designed to provide optimum mechanical performance
that results in a very high fatigue limit and residual breaking strength
after fatigue.
All components forming part of the Freyssinet HD anchorage system
have been intensively tested in independent laboratories, and the results have exceeded the main international acceptance criteria (over
95% of ultimate after fatigue testing).
The Freyssinet anchorage has been qualified according to latest PTI
and CIP standards.

Options
Freyssinet offers a wide choice of solutions to satisfy all functional and aesthetic
considerations.

Cohestrand®: cables for very aggressive environment
The Freyssinet HD stay cable can be adapted to provide better anti-corrosion performance for specific environments, by replacing Freyssinet Monostrand by Cohestrand®
strand.
This is a sheathed strand with seven galvanised or galfanised (coating composed of a
95% zinc and 5% aluminum alloy) steel wires, covered by a system capable of resisting
corrosion in very corrosive environments and also taking axial loads through the sheath
when required.
Freyssinet outer sheath: outstanding durability
Intensive research has lead to a range of durable outer sheaths.
The outer sheath is composed of two layers of co extruded HDPE: an inner black layer
and an outer coloured layer.
Tests have been carried out on all Freyssinet coloured sheaths to verify long term
colour stability. Close control during manufacturing guarantees a durability three times
longer than commercially available black and coloured polyethylene, for resistance to
ultra-violet induced oxidation and stress cracking.
A special HDPE sheath has also been developed with a silver coloured in-depth
metallized outer layer that resembles a brushed stainless steel sheath, while maintaining the ease of placement of HDPE sheaths and the presence of the helical rib
aerodynamic protection.
For any location in the world, Freyssinet can provide justification of sheath durability.

Compact sheath
For large cable-stayed bridges with a span in excess of 400 m, the drag of the wind
on the cables generates significant stresses on the pylon. In order to reduce this stress,
and to meet design requirements, Freyssinet has developed a compact outer stay pipe
that reduces the space between the bundle of strands and the pipe to a minimum. The
durability of this pipe is identical to the standard pipe.

Deviation saddles
When it is required that the stay cable continues through the pylon, Freyssinet
offers a multitube saddle based on the use of the Cohestrand strand in order
to take up the asymmetric frictional loads through the strand sheath.
Each strand is deviated individually in a specific tube, giving the following
advantages:
• Complete continuity of corrosion protection
• Possibility of individual replacement of strands
• Fatigue resistance identical to a standard stay cable anchor.

Complementary functions

Complementary functions are sometimes recommended, the most frequent
being:
• antivandalism tubes on the lower part of the cables;
• fire protection, when justified, to take account of the fire risk,
particularly on bridges carrying heavy traffic transporting
hydrocarbons and on bridges with back stay cables gathered
on an anchorage structure;
• light fittings fixed directly to the stay cables by a system
in accordance with electrical safety standards without disturbing
the aerodynamic stability of the cables.
All these options are already used on large well known works throughout
the world.

Aerodynamic stability
Stay vibration is a concern for bridge designers and owners.
By supplying and installing stay cables for the largest stay cable bridges in
recent years, Freyssinet has built up recognized expertise in the engineering
of stay cable vibration control.

Thanks to its worldwide experience, Freyssinet can offer a precise diagnostic
of the stability of stay cables and a wide range of vibration resistant devices
adaptable to each project.
Double helical ribs on outer sheaths
The shape of the ribs and the pitch of the helix they form around the sheath
is the result of intensive research based on wind tunnel tests carried out by
several laboratories.
The double helical ribs formed on Freyssinet stay cable sheaths deviate water
streams flowing along the cable and efficiently prevents instability due to
the combined action of wind and rain.
Internal dampers
Stay cables are sensitive to vibrations due to their low intrinsic damping.
Freyssinet has developed a patented annular internal damper system to
overcome this. These devices are located inside the anchor tubes and provide
a smooth outer shape.
These patented devices (the IED - Internal Elastomeric Damper, the IHDInternal Hydraulic Damper, and the IRD - Internal Radial Damper) damp
vibrations of all amplitudes to prevent harmful fatigue phenomena and
visible instability.
Freyssinet uses a specific computer model to calculate the damping needs
of the stays on a structure and to size the most suitable dampers as a function
of the stay cable characteristics.

IRD damper


External dampers
For very long cables or when the geometry requires it, external dampers are
more efficient than internal ones.
Two types of devices are available:
• the fixed external damper FED, composed of two piston
dampers and a support structure;
• the pendular external damper PED, also uses piston
dampers with a patented pendular lever system free to
move around a rod hinged on a fixed support.
Cross ties
Dampers may be insufficient in some exceptional cases. In this case, specific
cross ties have to be provided, particularly to cater for stay cable parametric
instability.
These cross tie cables sometimes called “aiguilles” are installed on each stay
cable plane and are continuous over their entire length. They have, for example,
been installed on the Normandie bridge.

Installation
Rapid and fully integrated in the construction style
The Freyssinet HD stay cable system has been used on more than a hundred
structures throughout the world, from the smallest to the most ambitious.
The individual installation of strands and automatic adjustment using the
Isotension® process patented by Freyssinet, enables outstanding flexibility
during installation while ensuring that forces within the stay cables are
uniform.
This process also facilitates the monitoring and maintenance of stay cables
to ensure long life.
Freyssinet works in partnership with the Advitam company to offer computer
aided systems for assistance with monitoring of stay cables and for permanent
acoustic monitoring.
The adjustable anchors offer the possibility to adjust the stay cable forces
using annular jacks with or without extension.

H1000
Stay Cable System
Freyssinet H1000 stay cable is a parallel strand system for use
in light structures. Applications include stay cables and hangers
for footbridges, arch bridges, suspended roofs and other cable
structures. The H1000 colored cable sheath provides a slender
cable that meets the expectations of architects for light structures

while the parallel strand technology ensures an unmatched
durability, making H1000 a sustainable technology.
H1000 Technology
The cable main tensile element consists of a bunble of seven wire strands that can
have a service load up to 265 tons. The H1000 is based on each strand being fully
independent. It has the following caracteristics:
• Each strand is individually anchored by jaws or swages in a steel anchorage block,
• Each strand is individually protected against corrosion by two redundant corrosion barriers,
• The strand bundle is protected by a colored polyethylene outer duct,
• The anchorages can be equipped with fork terminals.
H1000 stay cable system benefits from Freyssinet’s 30 year experience in stay cables, and conforms
to fib, PTI and CIP recommandations.

Parallel strand technology advantages
• Modularity: The number of strands is adjusted to the force in the cable
• Redundancy: Each strand is individually protected and anchored, which
provides a high level of safety
• Durability: The double nested corrosion protection barrier over the complete
cable including anchorages and the outstanding fatigue performance provide
an unmatched durability
• No long term effect: No loss in cable force, no cable elongation
after initial tensioning
• Standard components: Each cable is assembled on site out of standard
components, for a quicker delivery and eliminating risk of unexpected delay
due to cable damage during transportation or installation.

Freyssinet Monostrand
The main tensile element consists of a bundle of individually protected
parallel seven-wire T15.7 strands. This patented strand, the Freyssinet
‘Monostrand’, has outstanding durability both mechanically and against

ageing. The strand has a double corrosion protection barrier formed
by hot dip galvanisation of the individual wires of the strand before the
final drawing and a polyethylene sheath extruded around the strand.
The interstices between the wires and the sheath are filled with
petroleum wax.


Freyssinet H1000 Anchorage

The H1000 range includes five cable sizes for 1, 4, 7, 12, and 19 strands. Several H1000
anchorage configurations are available to cover the needs of the connection to the
structures.
An outstanding fatigue behaviour
Passive anchorage use swages specially designed for a high fatigue
resistance. Active anchorages use Freyssinet stay cable fatigue wedges.
Both comply with international recommadations regarding fatigue
design and have passed fatigue tests specified by CIP, fib and PTI:
2 million cycles with an amplitude of 200 Mpa, 45% GUTS as the maximum stress and a 10 mrad angular deviation. Thus the anchorage has
a fatigue resistance that is exceptionnal.

Anchorage options

FPH anchorage

The H1000 system is fitted with an adjustable lower anchorage and
fixed upper anchorage. At both ends, a fork anchorage or a cylindrical
anchorage can be used. Lower anchorages can be prefabricated using
swages with tensioning applied to the whole cable or partially prefabricated using jaws for monostrand tensioning (Isotension method).
Where jaws are used the anchorage is sealed with the patented
Freyssinet stuffing box. With swages, individual sealing devices are

installed on each strand. In both cases, the anchorage is completly
waterproofed by a double protecting barrier. Cable force adjustment is
provided by a threaded anchorage and a nut.

Outer pipe
An outer high density polyethylene pipe protects the bundle of strands improving the
cable aesthetics. The pipe is bi-extruded with an outer coloured layer and is specially
formulated for a high durability in sunlight: 50 to 100 years, depending on localisation,
supported by labotary testing.
A wide range of colours is available (non-contractual colour chart, non-exhaustive list)
