- An experimental study was conducted to evaluate the out-of-plane seismic behavior of representative bridge pier walls in the US. An analytical study was also carried out for the development and calibration of a model to determine the seismic response of typical pier walls. The parameters used were the ratio of the wall height to thickness, the vertical steel ratio, the confinement steel ratio, and the axial load index. A practical approach to relate the confinement reinforcement in the plastic hinge zones of bridge pier walls to the displacement ductility capacity was developed. The displacement ductility capacity of six typical pore walls containing confinement steel designed using the available code provisions was calculated. A computer program called PIER was written for the analytical model.
