• Abstract:
  The primary objective of this project was to investigate live load distribution over buried CIP-RC box culverts for the purpose of recommending the most suitable LLDF that can be used in design and load rating. The goals of the project were to: 1. Conduct a parametric investigation of buried CIP-RC box culverts that covers key parameters known to affect the distribution of wheel loads through the soil onto the culvert’s top slab and structurally through the culvert. 2. Analyze results from the parametric study to help evaluate the best LLDF for the design and load rating of CIP-RC box culverts. 3. Study the reliability of CIP-RC box culverts using different LLDF to ensure conformity with AASHTO LRFD BDS. 4. Provide DOTD with recommendations to assist in adoption in the Louisiana Bridge Design and Evaluation Manual (BDEM).
