| Abstract: | An investigation of the seismic behavior of 16 concrete filled rectangular steel tubular(CFRT) column specimens subjected to reversed cyclic lateral loading combined with constant axial compression force is reported.The experimental process was recorded and the failure pattern of the specimens was also described herein.From the test results,the displacement ductility of tested specimens was presented.The effects of various parameters including axial compression ratio,steel ratio of the composite columns,depth-to-width ratio of section and loading direction on the seismic behavior of CFRT columns were studied as well. |
