Performance - Based Design of Confinement Reinforcement in Reinforced Concrete Bridge Pier Walls for Out-of-Plane Seismic Loads

摘要

The objective of this research was to develop an approach that relates the confinement reinforcement in the plastic hinge zone of bridge pier walls to the displacement ductility capacity. An analyt - ical model to predict the seismic response of bridge pier walls was developed and verified using test data. A parametric study was conducted using a computer program named Pier to study pier walls with a wide range of parameters.
