Strengthening Piers to Resist Vehicular Collision

The need to strengthen existing piers to resist collision forces is being encountered frequently in multiple Florida Department of Transportation (FDOT) districts and a better understanding of strengthening methods with concrete collars, ultra-high performance concrete (UHPC) collars, FRPs or other optimized methods would make those repairs more cost efficient. This project will be a synthesis study of previously completed research with analysis performed to develop design details for strengthening with conventional concrete, UHPC, and CFRP wrap. Finite element methods for evaluating damage to bridge piers with applied impact load are well documented in the literature and can be followed to complete analysis for the three aforementioned repair strategies. The research shall include an appropriate baseline case for comparison. Areas where further research is required to develop design procedures and construction details will be identified.
