| Abstract: |
A bridge at the end of its lifespan tends to deteriorate at an exponential rate. Given the unique challenges of the Champlain Bridge located in Montréal, a customized inspection program was developed to monitor the condition and behaviour of the bridge approach spans. The cornerstone of this program is a set of customized inspection criteria to assess the degraded superstructure elements and the installed strengthening systems. An Integrated Grading System (IGS) rating the overall performance of a reinforced superstructure element was also developed. The IGS rating is based on an algorithm that feeds on inspection data from each individual component and considers the complexity of the interactions between the original structure and the added strengthening systems. This paper presents an example of the inspection criteria and IGS rating system developed specifically for the approach spans of the Champlain Bridge. |
