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.
