Project Details

Title:Methodology for Load Rating Double-Tee Bridges
Principal Investigators:Mostafa Tazarv, Nadim Wehbe, and Junwon Seo
University:South Dakota State University
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-523
RH Display ID:14192
Keywords:bearing capacity, collapse, deicing chemicals, deterioration, freeze thaw durability, girder bridges, live loads, structural analysis


This proposed project will develop a guideline to accurately load rate double-tee (DT) bridges located in South Dakota. To achieve this objective, both field and laboratory testing are recommended. Field tests will provide sufficient information to understand the live load distribution and dynamic load allowance specific to DT. The laboratory testing of full-scale salvaged DT girders will provide information to accurately calculate the actual capacity of deteriorated bridges. A load rating guideline based on visual identification of damage in DT bridges will be developed to further help engineers to rate those bridges in a timely and accurate fashion.
