Two research projects are being completed that investigate the behavior of curved steel bridges through field testing and numerical modeling. The first project studies the accuracy of various curved bridge analysis methods and computer codes through comparison of results to data recorded from controlled testing of an in-service structure.

The study of curved steel bridges is also being completed in association with the I-99 Advanced Technology Test Bed initiative. The effects of design, fabrication, and construction on the geometry and load distribution in a curved bridge system are areas in which further study and understanding are required. The construction of curved steel bridges in the I-99 Corridor provides a unique opportunity to investigate behavior not only during their construction but also throughout their service lives.
