To　improve　the　seismic　performance　of　high-pier　continuous　girder　bridges,　this　study　introduces　an　innovative　elliptical-bottom　rocking　pier.　Quasi-static　test　was　conducted　on　to　investigate　the　hysteresis　behavior　of　the　elliptical-bottom　rocking　pier.　The　results　demonstrate　that　the　elliptical-bottom　rocking　pier　has　self-centering　and　energy　dissipation　capabilities.　The　transition　from　a　fixed　state　to　a　rocking　state　was　induced　through　a　designed　failure　in　the　cover　plate.　To　evaluate　the　repairability　of　the　elliptical-bottom　rocking　pier,　the　damaged　specimen　was　repaired　and　the　quasi-static　test　was　repeated　again.　Compared　to　the　original　specimen,　the　seismic　performance　of　the　repaired　specimen　exhibited　a　slight　reduction　but　remained　satisfactory.　This　indicates　that　rapid　and　effective　structure　repair　of　the　elliptical-bottom　rocking　pier　can　be　achieved　after　earthquake.　A　finite　element　model　was　developed　to　accurately　capture　the　restoring　force　characteristics　and　damage　evolution.　Additionally,　the　design　suggestion　for　the　cover　plate　were　proposed　and　validated　in　conjunction　with　the　structural　stress　state　analysis.　©　2025　Institution　of　Structural　Engineers
