In　order　to　further　study　the　seismic　behavior　of　reinforced　concrete　hollow　bridge　columns　and　its　influencial　factors,　five　reinforced　concrete　hollow　bridge　columns　models　with　larger　ratios　were　built　and　tested　up　to　failure　under　the　combined　action　of　constant　axial　load　and　reversed　cyclic　lateral　load.　The　aim　is　to　evaluate　seismic　performances　of　all　the　five　models.　The　concerned　influencial　factors　inspected　include　longitudinal　reinforcement　ratio,　spiral　reinforcement　ratio,　axial　load　ratio,　and　seismic　performances　having　effects　such　as　failure　mode,　hysteretic　behavior,　load-carrying　capacity　and　ductility.　Analysis　on　the　experimental　results　indicates　that　the　anti-seismic　performance　of　reinforced　concrete　hollow　bridge　columns　is,　excellent　and　the　influences　of　the　factors　above　mentioned　obey　the　theory　of　reinforcement　concrete.　With　such　hollow　pier　in　engineering,　material　can　be　saved　dramtically,　while　enough　security　is　achieved.
