摘要：
The paper introduces 3 types of uniaxial stress-strain relationships of concrete filled steel tube by Pan Youguang, Susantha and Saenz, and performs finite element analyses of the axial strengths of 18 CTRC columns, studies the characters of three models, and comprises between the axial strengths from PEA and existed experiments. Results show these 3 types of model are all suitable for bearing analysis, but Pan's model is more accurate.
