“Some 25,000 bridges are in poor structural condition and pose safety and availability issues for users”

Bridge safety: Avoiding tragedy
Sénat information report no.609 on behalf of the sustainable development and regional development commission
Lodged on 26 June 2019

The most serious structural risks are not always visible. Visual inspections of bridges can only periodically report on visible issues in order to classify the structures according to quality standards (IQOA, VSC, etc.). Given the general ageing of infrastructure, including bridges, managers of those structures need a tool that gives them a clear view of their structure’s health. Our teams have created the OSMOS Weigh-in-Motion + Deformation (WiM+D®), a unique automated system combining weigh-in-motion techniques with an analysis of structural deformations. This new tool describes the loads passing over the structure and quantifies the exact operational impact on its structural condition.

Thanks to OSMOS WiM+D®, managers of structures can schedule appropriate maintenance programmes, spread out long-term maintenance costs and extend the lifespan of their bridges while ensuring the safety of users.

The OSMOS WiM+D® module lets you go beyond standard weigh-in-motion methods which are costly and restrictive in terms of installation. Simply by installing a few non-intrusive optical strands in the most serious deformation areas under the structure’s deck, we can count and weigh heavy vehicles and assess the exact impact of their crossing on the structure’s mechanical operation.

Our accurate data gives you key information about traffic over your structure, including speed and direction of crossing for each lorry, total weight and distribution of weight by axle, length and the maximum resulting strain on the structure. Heavy vehicles are automatically classified by weight and by direction of crossing. This information can then be viewed via the online interface: SAFE WorksTM. Optional video-surveillance cameras can also be installed at each site and linked to our measurement system. Each truck or exceptional convoy can be identified by its license plate and its timestamped passage. That information is also available online in individual files and is subject to GDPR regulations.

A statistical analysis of these dynamic events enables you to assess the structure’s operational rate and verify the deck's mechanical behaviour under moving loads: actual level of deformation, continuity, height of neutral axis, blockages on supports, etc.

Thanks to the OSMOS WiM+D®, you can track your bridge’s health in real time and understand the exact impact of traffic on its mechanical behaviour. This enables you to plan suitable maintenance, adapt the bridge’s service level if required, and prolong its lifespan.

OSMOS WiM+D® application: Example of monitoring a high traffic motorway bridge, with vehicle weight estimation and analysis of exceptional convoy impact

OSMOS was contacted by a European leader in toll road construction and management. The assignment: to monitor the behaviour of a motorway bridge in a setting that generates high traffic. The structure sits above another motorway and a railway, and is frequently used by heavy vehicles, including exceptional convoys. It is therefore important to check the impact of their crossings on the bridge’s condition.

In order to calibrate the OSMOS WiM+D® system to the structure’s response to that traffic, it was necessary to firstly perform load tests. This stage helped identify the dynamic signatures associated with various test loads and check the deck’s normal behaviour when vehicles cross it.

Following the load test, continuous structure monitoring was implemented in order to analyse and track changes in its mechanical behaviour due to internal and external stresses. By analysing those static data, we could study the gradual changes in the structure’s behaviours, including due to temperature variations and its natural ageing. The structure’s actual operating conditions were verified through dynamic data analysis.

Thanks to the OSMOS WiM+D®, the motorway bridge manager can now check the traffic at any time. By monitoring the bridge, several exceptional convoys over the authorised weight limit were detected and recorded. Those vehicles were subsequently identified using video-surveillance cameras linked to the monitoring system. The performed tests, continuous monitoring and information available on the SAFE WorksTM interface enabled the manager to assess the structure’s actual condition, plan remedial work to be undertaken and prevent costly, restrictive closures.

To be ever closer to its clients, OSMOS Group has the pleasure of announcing the release of its new services, suited to each type of structure. This is accompanied by the launch of a new website presenting each solution.

Managers of these different structures must contend with very different challenges, depending on the function of the structure: maintaining service levels for engineering works, preserving ancient heritage for monuments, optimizing operating conditions for industrial equipment, and ensuring public safety for establishments open to the public.

All clients can obtain dedicated support which is specific to them, managed by a specialized sales representative.

  • Infrastructures: OSMOS continuously monitors structural health and supports your asset management processes.

    By redefining maintenance operations and targeted repairs, based on the points of fragility identified in each structure, managers of public and private structures can optimize the use of their budgets and avoid unnecessary closures that are terribly costly and restrictive for users.
     
  • Ancient heritage: OSMOS can help you protect your ancient heritage for future generations.

    OSMOS’s mission is to provide conclusive insights on the actual state of a structure and monitor any mechanical behavior changes over time.
     
  • Industries: OSMOS monitors the structural integrity of industrial equipment and civil engineering works.

By combining monitoring and behavioral engineering, a structure’s exact state of health can be determined, namely including any emerging problems and their evolution over time, and the impact of operations on the behavior of the equipment and/or civil engineering structures can be tracked.

  • Buildings: OSMOS helps you preserve your buildings, over and above their appearance.

The unique expertise and information OSMOS provides can help the technical departments at companies that own and/or manage buildings, regional authorities, building administrators, construction experts and private firms to improve their management of structural risks, undertake appropriate maintenance work on their buildings, as needed, and ensure the safety of their buildings’ occupants.

Arnaud Surpas, OSMOS Senior Vice-President, explains that, “Our goal is to strengthen the support we offer our clients in managing their structures, but also to facilitate requests for information and the implementation of structural monitoring projects.”

 

About OSMOS Group:

A subsidiary of Eren Group and an expert in natural resource efficiency, OSMOS aims to extend the lives of structures and to optimize their upkeep, in order to save energy and economize on the materials needed for new builds.

With recognized expertise in France and abroad, the company has made a name for itself as a major player on the structural health monitoring (SHM) market. Thanks to its innovative technology and its expertise, OSMOS gives managers of structures and engineering and construction companies the possibility of continuously monitoring changes to their structures, in real time.

A listed structure since 2012 and a symbol of Angoulême’s industrial history, the tall Cheminée du Nil smokestack has been leaning for several years, the changing nature of which needed to be monitored. The city council launched a comprehensive assessment, which concluded that there was a need to implement safety measures while studies and then consolidation and restoration work were carried out.

 

The consolidation and restoration work on the Cheminée du Nil in Angoulême was entrusted to a consortium comprising the specialized construction firm Freyssinet Sud-Ouest, the structural engineering office ATES and the architectural practice BDF Architectures.

Upon its arrival at the building site in December 2018, Freyssinet Sud-Ouest entrusted the implementation of a structural instrumentation system to OSMOS, for the purpose of studying the smokestack’s mechanical behavior.

 

A structure under multiple stresses

With this type of slender, unprotected structure, the effect of the wind is by no means negligible. New sources of strain will soon be added to this, engendered by the construction work and requiring a real-time analysis of its dynamic behavior.

OSMOS has installed four Optical Strands at the base of the stack, to continuously measure structural deformation, in real time. A temperature sensor was also put in place, to determine the impact of temperature fluctuations on the structure’s behavior. In order to differentiate between the effects of the work and those of the wind, the monitoring system was supplemented by an air flow meter and a weather vane.

This set-up performs dynamic analyses based on the signatures of the recorded signals. Deformations are measured to check whether each dynamic event has led to any permanent or irreversible deformations characteristic of damage.

 

Initial results favorable to launch of the work

Since the monitoring system was installed in December 2018, data analyses have shown that the structure remained stable and that the planned work could be initiated.

The set-up recorded strong storms and a small earthquake, during which the smokestack vibrated, but fortunately without worsening its condition, as indicated by a comparison of its mechanical signatures before and after the events. Overall, the dynamic data demonstrated the solid resistance of the structure, with a return to normal behavior after each event. Despite the extraordinary intensity of the storms and the quake, the most extreme deformation amplitudes showed that these phenomena did not generate any damage to the structure. The monitoring will remain in place during the work.

 

Client testimonial:

Renaud Montes

  • Contract provides for the procurement, installation and commissioning of an advanced Real Time Structural Monitoring System (RTSMS)
  • Bridges are part of the New Double-Track High-Speed Railway Line Tithorea – Lianokladi – Domokos in Central Greece

 

Paris, May 7, 2019 – OSMOS Group, a specialist in the field of infrastructure monitoring and a subsidiary of EREN Groupe, is pleased to announce the signature of a contract between its Greek subsidiary OSMOS Hellas SA and ERGOSE SA, a subsidiary of the Hellenic Railways Organization (OSE), for the provision of Structural Health Monitoring (SHM) services for 14 large-scale bridges located in Central Greece.

As part of ERGOSE SA’s ambition to modernize OSE’s railway network, OSMOS Group has been chosen to provide monitoring services for 14 bridges forming part of the New Double-Track High-Speed Railway Line Tithorea – Lianokladi – Domokos.

 

Infrastructures such as bridges are exposed to a significant number of challenges which may be linked to operating conditions, traffic or the environment. Monitoring those structures closely is indispensable to ensure optimal operation and the highest safety standards.

 

Built on the most mountainous and difficult-to-access part of the Greek railway network, the 14 bridges are particularly exposed to increased levels of seismic activity. They have therefore been constructed with seismic insulation, incorporating the latest type of anti-seismic protection devices such as anti-seismic shock absorbers and hydraulic viscosity fluid dampers.

 

A pioneering project to provide critical data to ensure optimal operating conditions and the highest safety standards

 

The contract includes the procurement, installation and commissioning of an advanced Real Time Structural Monitoring System (RTSMS) for the bridges, over an initial period of four years.

 

OSMOS’ services have multiple purposes: to monitor the functioning of the bridges' seismic protection devices, to detect extraordinary events and related responses, and to assess the bridges’ overall condition and possible structural deterioration over time.

 

By leveraging innovative technologies and sophisticated tools, this comprehensive monitoring system will enable OSMOS to relay critical data regarding the structural behaviour of the bridges under operating conditions to ERGOSE SA in real time.

 

To this end, different types of connected sensors will be installed on critical parts of the bridges and will record live data linked to deformation, relative displacement, acceleration, temperature and wind velocity. The volume and type of data collected and processed by ΟSMOS, ERGOSE SA and specialist contractors demonstrate the scientific sophistication of the project.

 

This internationally pioneering project will permanently monitor large-scale, seismically-insulated railway bridges of a total length of 52 km for the first time, evaluating the transmission of seismic waves and their impact on the structured railway environment.
