To　examine　the　design　concept　and　structural　performance　of　the　high-rise　pier　with　CFST　reinforced　concrete　box　section　(the　CFST-RC　high-rise　pier　for　short),　the　Jinyang　River　Bridge　is　cited　as　an　example　to　analyze　the　function　and　load　bearing　behavior　of　each　part　of　the　pier　of　this　type　and　to　study　the　static　performance　as　well.　The　lattice　column　inside　the　pier　that　is　formed　of　concrete-filled　steel　tubes　is　the　main　load　bearing　structure　and　also　acts　as　the　stiffening　skeleton　in　the　construction　of　the　external　reinforced　concrete.　Each　steel　tube　is　encased　with　a　thin　layer　of　reinforced　concrete　to　improve　the　load　bearing　capacity　of　the　pier　and　the　reinforced　concrete　webs　of　each　pier　column　also　contribute　to　the　overall　anti-shearing　capacity.　The　software　MIDAS　Civil　was　used　to　compare　the　static　performance　of　the　CFST-RC　high-rise　pier　and　that　of　the　RC　thin-walled　hollow　high-rise　pier.　The　results　indicate　that　the　elastic　stability　coefficient　of　first　mode　vibrations　of　the　CFST-RC　high-rise　pier　is　bigger　than　that　of　the　RC　thin-walled　hollow　high-rise　pier　in　the　longest　cantilever　construction　state　and　the　completed　bridge　state.　When　the　diameter　and　wall　thickness　of　the　steel　tubes　are　increased　from　pier　top　to　pier　base　section　by　section,　the　stresses　in　the　steel　tubes　and　the　concrete　can　keep　the　same　along　the　pier　height.　The　stresses　in　the　encased　concrete　are　far　less　than　the　stresses　in　the　RC　thin-walled　hollow　high-rise　pier.　Therefore,　it　is　feasible　to　employ　the　thin　layer　of　low-strength　concrete.　©　2019,　Journal　Press,　China　Railway　Bridge　Science　Research　Institute,　Ltd.　All　right　reserved.
