To　investigate　the　seismic　performance　of　fiber　reinforced　polymer　(FRP)　jacketing　constrained　reinforcement　concrete　(RC)　hollow　section　bridge　piers　under　multi-dimensional　earthquake　action　cyclic　tests　of　five　RC　rectangular　hollow　section　benchmark　and　carbon　fiber　reinforced　polymer　(CFRP)　jacketing　confined　piers　specimens　were　carried　out　under　unidirectional　and　bidirectional　lateral　horizontal　repeated　loading.　The　failure　characteristics,　lateral　force-deformation　curves,　effective　loading　stiffness,　ductility　and　energy　dissipation　of　specimens　were　analyzed.　The　experimental　and　analytical　result　shows　that　the　damage　is　more　severe　and　failure　process　is　accelerated,　and　bearing　capacity,　ductility,　rigidity　and　energy　dissipation　are　decreased　under　bidirectional　earthquake　action.　The　CFRP　constraining　may　change　the　failure　location　and　mode　of　bridge　piers?and　improve　the　deformation　ductility,　plastic　deformation　and　energy　dissipation,　but　is　less　contribution　to　horizontal　force.
