| 摘要： | Prestressed concrete I-beams are used extensively as the primary superstructure components of bridges in Texas highways. The goal of this project was to solve one of the most troublesome problems in prestressed concrete beams: shear. Central to the problem is the lack of a rational model to predict the behavior of prestressed concrete structures under shear and the various modes of shear failures. Because of this defi ciency, all existing shear design provisions, including those in the ACI Codes and AASHTO Specifi cations, are empirical, complicated and have severe limitations. / NOTE: Project summary. / Supplementary Notes: See also PB2007-106637.
