ANALYSIS OF COMPOSITE BOX GIRDERS

The methods of analysis and design of box girders have been surveyed several times to date(l.4,l.5,l.6). The prismatic folded plate theory by Goldberg and Leve(l.7) considers the box girder to be made up of an assemblage of folded plates. This method uses two-dimensional elasticity theory for determining membrane stresses
