Behavior of Reinforced Concrete Members
Reinforced concrete bridges must be designed so that their performance under load does not go beyond the limit states prescribed by AASHTO. Service limit states relate to bridge performance. Extreme event limit states are unique occurrences with return periods in excess of the design life of the bridge. Earthquakes, ice loads, vehicle collisions, and vessel collisions are considered to be extreme events and are to be used one at a time. The AASHTO bridge specifications present unified design provisions that apply to concrete members reinforced with a combination of conventional steel bars and prestressing strands. Ductility in reinforced concrete beams is an important factor in their design because it allows large deflections and rotations to occur without collapse of the beam. A tension field theory has been developed to determine the relationships between these parameters and to predict the shear strength of plate girder webs.
