Abstract:Civil highway infrastructure is susceptible to deterioration caused by aging, harsh weather conditions, and natural hazards. Also, the rapid growth of traffic volume, particularly vehicle overweight enforcement, on degraded bridges increases the safety concerns and maintenance challenges for transportation agencies. These factors can adversely affect the bridges and highways' pavement condition and safety and cause serious issues to them such as fatigue, cracks, or even collapse. Intelligent Traffic Systems (ITS) and Structural Health Monitoring (SHM) have the potential to save highway infrastructure managers millions in traffic control and maintenance operations, respectively. The integration of the two systems is more attractive to practitioners because it brings improved value. That is, on one hand, ITS can make SHM estimates more accurate by providing load information. On the other hand, SHM can complement ITS data to help assess the impact of traffic on bridge condition. By fusing system information, less sensors may be required overall. Thus, an integrated, cost-effective monitoring system can be beneficial for the transportation agencies to first, detect the overloaded vehicles without disrupting the traffic, and second, regularly monitor the bridge integrity without imposing much additional cost. This study demonstrates the value of the fusion of SHM and ITS data for global bridge asset management using a high fidelity finite element model of a concrete box girder bridge and various combinations of traffic patterns and bridge damages.
