摘要：In this paper, the shear strength of circular reinforced concrete (RC) columns was obtained using numerical models based on a modified compression field theory that enabled the sectional analysis of the beams. By comparing the computational results with previous experimental results, we were able to assess the suitability of this numerical model for estimating the shear strength of circular RC columns. Additionally, the validity range of the shear strengths was evaluated by substituting rectangular column sections for circular column sections. The relationship between the shear strength of the circular RC columns and the shear span-depth ratio were also discussed. On a final note, we examined by calculating the shear strength of the numerical models by using equations to estimate the concrete strength of confined concrete.
