Comparison between the theoretical and the measured moment-curvature relationships of the confined R/C Columns was conducted to investigate the factors influencing the theoretical results of the columns. The strain gradient across the section and the assumption about spalling of the cover concrete in analysis have been found to be major factors influencing the theoretical flexural behavior of the columns. To better estimate the flexural behavior of confined concrete columns, a new method in which the effect of the two factors above-mentioned have been taken for account is proposed to calculate the moment-curvature relationship of the confined column. Satisfactory agreement between the experimental results and the analytical ones calculated by the proposed method has been observed.
