Condition monitoring and rating of bridge components in a rail or road network by using SHM systems within SRP

Abstract
The safety and performance of bridges could be monitored and evaluated by Structural Health
Monitoring (SHM) systems. These systems try to identify and locate the damages in a structure and estimate
their severities. Current SHM systems are applied to a single bridge, and they have not been used to monitor
the structural condition of a network of bridges. This paper propose a new method which will be used in
Synthetic Rating Procedures (SRP) developed by the authors of this paper and utilizes SHM systems for
monitoring and evaluating the condition of a network of bridges. Synthetic rating procedures are used to
assess the condition of a network of bridges and identify their ratings. As an additional part of the SRP, the
method proposed in this paper can continuously monitor the behaviour of a network of bridges and therefore
it can assist to prevent the sudden collapses of bridges or the disruptions to their serviceability. The method
could be an important part of a bridge management system (BMS) for managers and engineers who work on
condition assessment of a network of bridges.
