Vehicles often collide with bridges. However, there are no available guidelines for bridge inspectors to assess damage and to make repair decisions. This project addresses this gap by investigating the behavior of steel girder bridges subjected to vehicular collision through (1) performing non-destructive field testing, (2) developing validated numerical models, and (3) performing parametric investigations to extend research findings. Field testing was performed using Digital Image Correlation (DIC)—a portable, non-destructive, photographic measurement technique that can measure three-dimensional strains based on pattern recognition. Ultimately, the project culminated in assessment guidelines for bridge inspectors to evaluate damaged bridges for repair. This project can benefit Indiana Department of Transportation (INDOT) business processes by potentially reducing the number or amount of repairs, leading to direct cost savings and longer lifespans for bridges.
