THE IMAGE

In the night of 30 to 31 July 2018, Freyssinet slid out the old deck and slid in the new composite deck (steel and concrete) of the Marly-le-Roi railway viaduct. This operation, which is considered the most complex part of the project, consists of sliding first the old deck and then the new one sideways using a system of hydraulic jacks. Built in 1883,

the bridge is located on Line L of the Transilien rail network in a very built-up area near Marly-le-Roi station, and carries nearly 150 trains each day.The project was carried out in five phases over a two-and-a-half-year period, limiting the disruption to rail traffic to a few weekends in 2017 and then seven consecutive weeks in the summer of 2018 to complete the work.

Structure Magazine provides a twice-yearly overview of our projects worldwide. The magazine complements our web site www.freyssinet.com, which contains more news and information about our business.

Strong solution driven culture The diversity of Freyssinet’s activity today is reflected in the

range of projects highlighted in this edition – new bridge construction; upgrading, repair and strengthening of existing structures; seismic protection; applied in industrial

facilities, dams as well as civil infrastructures.This diversity is a natural response to your changing needs – and I believe the key driving principles of identifying the right solution are efficiency of design and optimisation of materials. Our engineers are instinctively tuned to this. Indeed, having celebrated our 75th anniversary in 2018 – we are reminded that these were also the guiding principles of our founder, coupled with an acute attention to detail. Many of you no longer carry the same technical and operational capacity you did in the past, as you turn towards specialist contractors with a strong solution driven culture. This has created opportunities for us to partner and assist early in the conception of the project, working closely with you, from concept and diagnosis through to execution and monitoring. Marly-le-Roi viaduct in France and widening of the Rande Bridge in Spain are good examples of this.You can also look at some of the high-profile projects this year, for example, the Atlantic Bridge in Panama, the New Coastal Road viaduct in Réunion and the restoration of Kpémé Wharf in TogoWe continue to develop new solutions - high strength concrete applications and digitalisation of our prestressing systems. Implemented for the first time on the new Kosciuszko Bridge in New York in 2017, our stay cable fire protection is being deployed for numerous projects and has been applied in buildings. Freyssinet has also developed a new system of stay cables with LED lights. This turnkey solution gives bridges a unique and customizable aesthetic appearance while retaining the cables’ aerodynamic properties.I hope you enjoy the magazine. With a burgeoning order book, which bodes well for our continued development, we look forward to sharing our new projects in our next edition.

The technology

The problemBuild or retrofi t any structures (bridges, buildings, tanks, etc.) in seismic areas granting the resistance to earthquakes without damages, minimizing the maintenance costs.

The solutionFreyssinet ISOSISM® range of products provides the possibility to tune the period of vibration of the structure and to damp the earthquake energy, so the horizontal accelerations decrease and the structure can slide smoothly as a stiff body without deformations over the isolation plan. Hundreds of structures worldwide have been protected through the installation of the Freyssinet ISOSISM® isolators.

ISOSISM® HDRB : isolators composed by high damping rubber compound and steel layers. They are able to support vertical loads and allow horizontal movements through tailor designed stiff ness, they are usually installed at building foundation level or between deck and piers cap of bridges and viaducts.

ISOSISM® LRB : cylindrical isolators similar to HDRB but with a lead core in the center to provide a higher amount of damping.

ISOSISM® PS : curved sliding surface isolators made by one or two steel concave sliding surfaces machined with a suitable curvature radius and covered by stainless steel sheet. The convex element coupled to the sliding surfaces has the same radius and it is equipped by special sliding material Isoglide® to grant high wearing resistance and steady friction. They can stand vertical loads and large horizontal displacements and have very good re-centering capacities.

The advantagesThe reduction of the seismic horizontal forces transmitted from the ground to the structure allows the reduction of the structural elements size and therefore their cost. Moreover, the structure remains in elastic fi eld, thus avoiding any damages and maintain operability. The Freyssinet ISOSISM® isolators are available in a wide range covering all the needs required by the seismic protection engineering worldwide. Designed, manufactured and tested according to all international standards, they fi t for installation in either new and existing structures.


1976 A new stadium for Montreal17 July 1976: in the brand-new Montreal stadium, an excited crowd watches the opening of the Summer Olympics. Nicknamed the «Big O» due to its shape when seen from the air, the stadium was designed by architect Roger Taillibert and built with the help of Freyssinet, which installed all the prestressing for the structure and the associated velodrome. The work started in April 1974 and came to an end on 9 July 1976, just a few days before the start of the Olympic Games!
