Retrofitting of reinforced concrete box culvert using fiber reinforced polymer composites - a numerical investigation - Vol.95(2), Feb - Thane ACC LTD 2021 - 7-15p.
Reinforced concrete box culverts are subjected to moving loads and weathering actions which results into faster deterioration mainly in the form of cracking/spalling of concrete leading to corrosion of reinforcements. Corrosion causes loss of materials which reduces the service life. Retrofitting a deteriorated box culvert with fiber reinforced polymer (FRP) composites can effectively enhance its performance and durability. In the present work, a three-dimensional finite element model has been developed for a typical box culvert and different levels of deterioration along with a retrofitting strategy with FRP have been simulated. The analysis shows a significant improvement in performance of the retrofitted box culvert.
