For　reinforced　concrete　(RC)　double-column　medium-height　bents　(DCM　bents)　with　link　beams,　RC　link　beamcolumn　joints　are　susceptible　to　damage　under　strong　earthquakes,　which　may　cause　significant　inconveniences　for　maintenance　and　repair　following　earthquakes　of　the　bridge　structure.　To　improve　the　seismic　performance　and　facilitate　post-earthquake　repair　of　DCM　bents,　rocking　link　beams　(RLBs)　were　applied　in　double-column　bents　to　replace　traditional　cast-in-place　link　beams　based　on　the　merits　of　rocking　structure　with　selfcentering　capacity　and　damage　controllability　in　this　study.　The　mechanical　behavior　and　force　analysis　of　the　DCM　bent　with　rocking　link　beams　were　introduced.　Then,　the　hysteretic　behavior　of　rocking　link　beams　based　on　steel　angles　and　post-tensioned　(PT)　tendons　was　investigated　through　experimentation,　and　the　test　results　showed　that　the　RLB　exhibits　a　flag-shaped　hysteretic　behavior　with　smaller　residual　deformation　and　greater　bearing　capacity　compared　with　that　of　the　RLB　without　PT　tendons.　Subsequently,　the　quasi-static　cyclic　loading　tests　of　the　DCM　bent　with　the　RLBs　specimen　were　carried　out,　and　a　DCM　bent　and　a　DCM　bent　with　RC　link　beams　were　also　tested　for　comparison.　The　experimental　results　show　that　the　DCM　bent　with　RLBs　suffered　the　least　damage　compared　with　the　DCM　bent　and　DCM　bent　with　RC　link　beams,　and　there　was　no　obvious　damage　in　the　beam-column　connection　joints.　In　particular,　the　DCM　bent　with　RLBs　exhibited　excellent　hysteresis　behavior　with　a　large　carrying　capacity,　stable　energy　dissipation,　and　no　significant　deterioration　in　strength.
