Developing the Load Distribution Formula for Louisiana Culverts

The objective of this study is to develop live load distribution formulas that can be used to represent the dimensions of the affected area over buried cast-in place (CIP) reinforced concrete box culverts through an extensive parametric study that covers attributes of existing culverts in Louisiana’s bridge inventory. The proposed formulas will take into account Louisiana standard details for negative moment reinforcement at exterior corners. The developed formulas will be validated using data from LTRC project 16-3ST “Live Load Rating of Cast-in-Place Concrete Box Culverts.”
