Abstract:
The response modification factors for circular reinforced concrete single column bridge bents were calculated for a wide range of periods based on three target values: the capacity to demand displacement, displacement ductility ratio, and longitudinal reinforcement ratio. The validity of using the ratio of capacity to demand displacements as a check in the column design process and the effect of confinement steel ratio on the response modification factors were also investigated.
