Abstract: Considering the effect of the flange on the shear capacity of reinforced concrete (RC) beams without stirrups, a shear capacity calculation formula based on the crack sliding model is proposed for RC beams without stirrups in this paper. Test data of 444 rectangular section beams and 172 T-beams were collected to verify this calculation theory, and the calculation results were compared with domestic and international design codes. The collected datasets were analyzed using five common machine learning models. The results show that the shear capacity calculation method proposed by the codes of each country is in good agreement with the test results. Compared to the calculation of the codes, the addressed calculation method in this study is more accurate and can effectively account for the contribution of the T-beam flange to the shear capacity. The machine learning models selected in this paper exhibit desirable accuracy on the test set, which demonstrates the applicability of the machine learning models in the calculation of shear capacity for reinforced concrete beams.
