Abstract: The general situation of earthquake-resistant behavior experiments of high concrete columns reinforced with concrete filled steel tube is presented.Based on the experimental results,the numerical analysis of load-moment interaction diagram for the columns is completed using strip finite element analysis method.The calculation results are in basic agreement with those of the experimental values,so the numerical analysis method can be used to determine the ultimate bearing capacity of the columns under eccentric compression.
