The overarching primary objective of the proposed research is to experimentally develop and assess a new double composite steel bridge system that allows for the construction of long span bridges using hot rolled steel beams. Various sub-objectives are thought for the complete assessment of the proposed system including: 1) Evaluating the system characteristics including stiffness, strength, and ductility; 2) Assessing the demand in slabs and beams including moment, shear, and deflection under specified AASHTO loading; 3) Comparing the response between the proposed bridge system and conventional bridge superstructures; 4) Evaluating the use of rolled beam sections covering up to 44 inches in height.
