A　method　is　proposed　to　evaluate　the　aseismic　performance　of　existing　concrete　piers　based　on　the　effectiveness　assessment　of　reinforcement　construction　details.　The　influence　of　reinforcement　construction　details　on　the　aseismic　performance　of　the　piers　are　discussed　from　four　aspects:　the　longitudinal　reinforcement　and　stirrup　anchorage　structure,　the　stirrups　to　prevent　buckling　of　longitudinal　reinforcement　between　two　stirrups,　the　stirrups　to　prevent　buckling　of　longitudinal　reinforcement　through　stirrups,　and　the　stirrups　to　confine　core　concrete.　By　the　proposed　method,　the　shear　capacity,　flexural　capacity,　and　ductile　deformation　capacity　can　be　calculated　based　on　the　effectiveness　assessment　of　structural　details,　and　thus　the　seismic　performance　of　bridge　piers　can　be　assessed.　The　performance　of　stirrups,　longitudinal　reinforcement,　concrete,　and　other　materials　can　be　predicted　when　the　earthquake　occur.　The　weak　parts　with　bad　seismic　performance　in　the　member　can　be　shown,　which　can　provide　reference　for　the　strengthening　of　piers.　©　2016,　Editorial　Office　of　China　Civil　Engineering　Journal.　All　right　reserved.
