Bridge Design .increasing the cost-effectiveness of steel box girder bridges in the future. DESIGN FOR ECONOMY Fewer Boxes Steel box girder bridges are inherently more efficient than conventional plate girders and reduce the amount of steel required for bending and shear by virtue of their torsional stiffness and enhanced live load distribution. He demonstrated how to use Midas civil to model curved steel box girder bridges as well as go over the procedure he followed to perform load rating. Last but not least, he discussed the modeling of end diaphragms with plate elements, the use of elastics links, and how to verify load rating results with analysis and design output.
