Seismic Performance of a Model Reinforced Concrete Bridge Pier Before and AfterRetrofit

摘要

A series of experimental and analytical studies was performed on a 1/3 scalemodel pier before and after retrofit. The pre-retrofitted model pier was tested under quasi-static inelastic loading and was governed by flexure at moderate drift levels, but ultimately limited by the cap beam-column joint shear capacity and a subsequent loss of bond strength in improperly anchored column longitudinal
