Abstract:
A structural system comprised of prefabricated deck units spaced along longitudinal load-carrying members with tensioned structural elements, typically anchored in longitudinal load-carrying members, which produce longitudinal axial compression in these units. During construction, prefabricated deck units are erected on top of and supported by the longitudinal load-carrying members via leveling devices. Leveling devices permit relative motion between the longitudinal load-carrying members and the prefabricated deck units, except at two ends of a structural unit, where deck connection units are connected to longitudinal members. In the longitudinal direction, each girder line contains more than one girder or girder segment and the girders or girder segments are not continuous during tensioning. The girder support allows the girder or girder segments to move in the longitudinal direction. When the tensioned structural elements are stressed, the longitudinal component of the tensioned structural element can become compression in the deck.
