Monitoring offers multiple advantages to bridge owners, architects, safety authorities and construction companies:
- Monitor stability of the load distribution over time to verify how wear and environmental factors affect the safety status of the bridge (long term behaviour)
- Compare actual load distribution with the theoretical load distribution
- Dynamic (short term) behaviour of the bridge due to traffic (trains, cars, trucks)
New developments in fibre optic sensing now enable to use this technology for bridge monitoring.
The performance evaluation report compares the fibre optic strain gauges with their electric equivalent.
