Abstract: Analytical and experimental studies are made on a simple span, single cell box girder bridge model with orthotropic deck having open ribs, to find and compare stresses under static loads. A method is proposed to find stresses in the cantilever portion of the deck. Torsional stresses in the box cell due to eccentric loading is calculated using the analogy to a beam on elastic foundation. For experimental studies the model is fabricated from plexiglass whose material properties are also determined.
