Seismic Performance Assessment of Deteriorating Reinforced Concrete Box Culvert

Abstract

A culvert is a crucial component of highways whose proper operation is connected indirectly to the state's economy and the effectiveness and safety of road transportation. Therefore, it is crucial to assess the culvert structure's safety. In this work, a seismic assessment of undamaged and damaged reinforced concrete box culverts is performed. The deterioration in culvert slab thickness over time due to corrosion is considered. The structure was subjected to seismic loading along with standard static loading to observe the performance of a box culvert. The results show that the seismic response of culverts would be influenced by aging and deterioration of slab thickness from its original conditions. The finding of this study highlights the importance of considering the effect of corrosion on the slab thickness when assessing the seismic performance of culverts, as it can have a significant impact on the structure's safety.
