A reinforced concrete(RC)column and four concrete filled GFRP tubular columns,which are subjected to combined axial compression and lateral cycle loading,were tested in order to investigate the seismic performance of composite construction concrete filled glass fiber reinforced polymer(GFRP)tubular(CFFT)columns.The results indicated that concrete-filled GFRP tubular columns exhibit considerable influence over the seismic performance of columns by providing hoop confinement to the core concrete.The concrete filled GFRP tubular colunms exhibit significant improvement over traditional RC columns in both ultimate strength and ductility.Different column-footing connection modes do not affect the strength and ductility of concrete filled GFRP tubular columns.The strength of concrete filled GFRP tubular columns under high axial compression load conditions are slightly increased,however,ductility declined.
