Book excerpt: Pretensioned concrete box beams have been used in highway bridges for more than half a century. Due to their geometry, they have often been used as a viable alternative to the classic I-shaped girders. Box beams are highly effective in cases where speed of construction is a priority. However, the detailing and design of box beams are more complicated than that of I-shaped girders. The flow of forces at the beam's end blocks must be understood in order to detail reinforcement adequately. The following were the objectives of this research study: (1) quantify the demands placed on box beam end blocks upon prestress transfer, (2) characterize the demands placed on box beam end blocks upon the application of superimposed loads, (3) evaluate the effects of alternative void geometries at skewed ends of box beams on curing temperatures, (4) based on the knowledge gained, improve the box beam end blocks, (5) test the improved end block under worst case scenario demands at prestress transfer and under extreme loading conditions, and (6) validate currently used shear strength design methodologies in their application to pretensioned box beams. In order to achieve these objectives, an experimental program was conducted. The experimental program included the load testing of ten 4B28 and five 5B40 box beams, for a total of twenty nine load tests. The influence of several factors that distinguish box beam behavior from the better-understood I-shaped girder behavior was studied. Additionally, the experimental program included the fabrication, instrumentation and early-age behavior study of five 5B40 box beams. The first three beams were used to assess the behavior of box beams fabricated with the current Texas Department of Transportation (TxDOT) standard details (from December 2006). The fourth beam incorporated modifications to the standard reinforcement details based on the observations made through the study of the first three 5B40 box beams. The last specimen corresponded to a new box beam cross section (5XB40) optimized to be used in a spread-box beams configuration.
