United States Patent Patent No.: US 7.627,921 B2
A structural Support system employs a modified inverted box girder design for improved performance and ease of fabrica tion. Each girder of a series of girders is formed with an upper flange section, a set of web sections extending from opposite lateral sides of the upper flange section, and a base section below the web sections. The base section includes individual flanged footings that project generally towards one another. The particular cross-sectional configuration of each girder may be formed by bending a continuous steel plate along at least a first set of preselected parallel lines to establish a set of upper continuous transitional bends with the upper flange section therebetween, as well as a remainder portion forming at least the set of web sections. A deck is coupled with the series of girders to form the structural Support system.
