Bridge Structural Health Monitoring Systems
Furthermore, the data resulting from a monitoring program can be used to improve the operation, maintenance, repair and replacement of a structure based on reliable and objective data. To implement corrective measures and maintenance actions, monitoring must enable the timely detection of conditions or behaviours that could deteriorate the bridge, make it unsafe, or potentially result in its failure.
Why is it important to monitor a bridge?
- To ensure bridge safety
- To safely extend the lifetime of a deficient bridge
- To improve knowledge and understanding of a structure
- To optimize operations and maintenance costs
Benefits of the Testindo Group's Integrated Bridge Structural Health Monitoring System
- Integrated solutions The Testindo Group provides Integrated Structural Health Monitoring Solutions for bridges, based on advanced fiber optic technologies and conventional sensors. The Testindo Group also integrates local corrosion sensors and other third party transducers for additional information. All sensing technologies are seamlessly integrated into a single database and user interface.
- SHMLive Through the SHMLive service, the Testindo Group offers a comprehensive solution for bridge monitoring. This includes the design of the system, its delivery and installation, maintenance and operation, web access to the data and data analysis by experienced engineering partners, all for a fixed monthly fee.
- Ensure security, assessing real conditions of the bridge Structural Health Monitoring aims to provide more reliable data on the real condition of the structure, observe its evolution and detect the appearance of new degradations. Furthermore, it provides a comparison between design and real (monitored) behavior and confirms or denies design performances. A structural monitoring system installed on a bridge is able to greatly improve the security for the structure itself and for the users as well
- Extend the lifetime of ageing bridges Many structures are in much better condition than expected or observed by visual inspection alone. In such cases, monitoring will allow the owner of a bridge to increase the safety margins without any intervention on the structure. Owners can take advantage of better material properties, over design and synergetic effects, to extend the lifetime or load-bearing capacity of structures. If repairs are really needed, the monitoring data will help designing an optimal repair strategy.
- Quality assurance A monitoring system provides information on the quality of the material used in the construction as well as on the structural design calculus during and after the construction.
- Improve knowledge of complex bridges Improve and increase knowledge on structural behavior of complex or novel bridges on the long-term and when new materials, new construction technologies and new structural systems are used. For bridges made of unusual material, monitoring is an effective way to understand the real behavior and to refine behavioral theories. Monitoring helps creation, knowledge’s improvement and accurate recalibration of numerical models.
- Assessing bridge safety immediately after a major event Understand and assess possible damages and failures caused by extraordinary events such as earthquakes, impacts, strong winds, storms or explosions. This ability allows a bridge manager or consultant to make a preliminary assessment of whether the safety of the bridge has been seriously compromised.
- The Testindo Group: a dependable partner for instrumentation project management The Testindo Group will support the owners in all phases of a project, from system design to installation, commissioning and training. Through the experience and commitment of the Testindo Group, any monitoring needs will be met. The Testindo Group has been instrumenting critical structures, including dams and nuclear power plants, for more than 60 years. Its worldwide network of system integrators provides a competent local support for any project. All the systems come with a 10 year warranty on the availability of spare parts.
