The Pennsylvania Department of Transportation designed and constructed a posttensioned segmental concrete box-girder bridge at the Pennsylvania Transportation Research Facility (Test Track) located at Pennsylvania State University. The bridge consists of two independent curved girders with a simply supported span length of 121 ft. (36.9 m). The cross section of each girder consists of a box section with side cantilevers. The main objectives of the research program for the segmental bridge were to make field measurements on the full-scale bridge, to study the behavior of the bridge under normal truck loadings, and to study the overload behavior to establish actual safety factors. The accomplishment of these objectives required temperature studies, static load testing of the bridge, overload testing of the bridge, laboratory testing of individual segments, andd eoretical studies. This research resulted in many observations for the design of segmental bridges concerning temperature, longitudinal bending, and transverse bending. (Author)
