Prestressed　concrete　(PC)　pipe　pile　has　poor　seismic　performance　compared　with　ordinary　concrete　piles.　To　improve　the　performance,　a　new　type　of　mesh-constrained　PC　pipe　pile　is　proposed.　Through　the　quasi-static　test　of　four　PC　pipe　pile　specimens,　which　are　divided　into　two　groups　under　different　axial　compression　ratios,　effects　of　reinforcement　form　and　axial　compression　ratio　on　their　seismic　performance　were　investigated.　One　group　had　a　new　type　of　meshed　constraint　and　the　other　had　common　spiral　constraint.　The　axial　compression　ratios　of　each　group　were　0.3　and　0.5　respectively.　The　failure　process　was　recorded　in　detail,　and　the　hysteresis　curve,　skeleton　curve,　load-bearing　capacity,　deformation　ability,　stiffness　degradation　curve　and　energy　consumption　capacity　of　the　test　specimens　were　obtained.　Results　show　that　all　test　specimens　were　subjected　to　flexural　failure,　and　the　ductility　factor　was　between　2.99　and　3.96.　The　meshed　constrained　test　specimens　had　large　energy　consumption,　and　its　hysteresis　loop　was　fuller　than　the　spiral　constrained　specimens.　The　load-bearing　capacity,　ductility　and　energy　dissipation　capacity　of　the　specimens　were　greatly　affected　by　the　axial　compression　ratio.　The　larger　the　axial　compression　ratio,　the　greater　the　load-bearing　capacity　and　the　worse　the　ductility　and　energy　dissipation　capacity.　A　formula　of　flexural　capacity　of　the　PC　pipe　piles　with　meshed　constrain　stirrups　is　proposed　and　the　formula　of　the　PC　pipe　piles　subjected　to　the　high　axial　compressive　ratio　is　modified.　©　2019,　Editorial　Board　of　Journal　of　Harbin　Institute　of　Technology.　All　right　reserved.
