Insufficient　lateral　deformability　of　columns　within　the　high　axial　force　is　the　main　failure　mechanism　of　subway　stations　under　earthquake　loading.　This　study　proposed　applying　reinforced　concrete　truncated　(RCT)　columns　to　improve　the　seismic　capacity　of　subway　stations.　The　seismic　tests　of　RCT　columns　and　cast-in-place　(CIP)　columns　were　conducted　first.　Then　the　seismic　capacity　of　subway　stations　with　RCT　and　CIP　columns　was　discussed　by　push-over　analysis.　After　that,　the　seismic　response　of　subway　stations　with　RCT　and　CIP　columns　was　simulated　by　considering　both　horizontal　and　vertical　ground　motions.　Numerical　results　presented　that　the　vertical　performance　of　both　structures　had　no　obvious　difference.　However,　the　earthquake-induced　horizontal　deformation　of　the　structure　with　RCT　columns　was　smaller　than　that　of　the　structure　with　CIP　columns,　then　the　structure　with　RCT　columns　experienced　lighter　damage.　Therefore,　RCT　columns　can　be　applied　to　improve　the　seismic　performance　of　subway　stations.
