Abstract: A cost-effective orthotropic deck bridge panel which is capable of being standardized to facilitate the use of orthotropic decks on short span bridges. Inclusion of a concrete deck in the panel simplifies fabrication details, thereby increasing the economic viability of the disclosed orthotropic deck panel in short span bridge projects. Shortcomings in fabrication of steel support ribs of the panel are overcome by using a cold roll-forming process instead of a press brake to form longitudinal bends in sheet material. The cold roll-forming process further allows camber to be introduced in the support ribs, thereby eliminating an extra manufacturing step.

Abstract: A shallow single plate cold roll formed steel tub girder member is fabricated from unheated steel plate material by a cold roll-forming process which eliminates longitudinal welds and induces camber in the tub girder member.

Abstract: A new modular orthotropic steel bridge deck, and its manufacturing method, which introduces the design standardization of the orthotropic steel bridge deck designs, thereby, leading to cost-effective solutions by avoiding the complexities and costly details that are unnecessary for orthotropic steel bridge deck and short span bridge applications.
