Bridge system using prefabricated deck units with external tensioned structural elements

摘要

A bridge system comprised of prefabricated deck units spaced along longitudinal load-carrying members. Tensioned structural elements are external to a plurality of the prefabricated deck units and produce longitudinal axial compression in these units. The tensioned structural elements can be deviated relative to the horizontal plane of the prefabricated deck units, subsequently enhancing the load-carrying capacity of the longitudinal load-carrying members. Leveling devices that permit relative motion between the longitudinal load-carrying members and the prefabricated deck units are provided. The leveling devices allow for the tensioned structural elements to provide longitudinal compression to the prefabricated deck units independent of the longitudinal load-carrying members.
