• Abstract:
  The 2007 AASHTO LRFD Bridge Design Specifications contain prescriptive ; requirements for the quantity and placement of confinement reinforcement located in the bottom ; flange of pretensioned concrete I-girders. This chapter proposes a rational model that can be ; used to design confinement reinforcement as an alternative to the prescriptive requirements of ; AASHTO LRFD. The model considers a wide range of conditions and variations, yet is ; intended to be practical enough for use by bridge design engineers. Variables in the design ; model include: flange and bearing geometry, strand size and placement, effective prestress ; force, concrete and steel material properties, and the effects of steel bearing plates. Derivation of ; the model is presented, and the model is compared to experimental results from the published ; literature.
