Assessment and Repair of Prestressed Bridge Girders Subjected to Over-Height Truck Impacts (OHTI)
Having adequate reliable infrastructures, including bridges, has been crucial to the process of economic and social development of any country. Bridges are exposed to man-made and natural hazards such as earthquakes, floods, and impact loads. Vehicles and vessels may impact bridge columns, piers, and girders causing severe damage and yielding losses of human lives and economy. Based on bridge failure incidents occurred between 1967 and 2006, vessel and vehicles impacts are the second highest cause of bridge failure in the U.S. Failure occurred due to damage to bridge girders and columns. This project focuses on the behavior and repair of bridge girders subjected to over-height truck impacts. OBJECTIVES: Vehicle impact is one of the major causes for bridge collapse in the U.S. The overarching goal of this project is to assess the damage to and repair of bridge girders due to the over-height truck impact using comprehensive experimental testing and analytical models. In particular, this project aims to determine: • The remaining carrying capacity of bridge girders damaged due to over-height truck impact which will allow stakeholders (e.g., state department of transportation engineers) to prioritize girders needing repairs. • Determine the carrying capacity of the damaged girders after being repaired using different repair measures. The repaired beams will be investigated under static and fatigue loads to determine their capacities.
