JGJ 138—2016, СИ 3-78, YB 9082—2006, AISC 360-16, and YE Lie-ping's formulas were used to calculate the ultimate flexural capacities of 51 collected specimens of steel reinforced concrete (SRC) beams with rectangular sections. The calculated results were compared with the test values. The ranges of parameters of the collected specimens and the reasons for the calculation errors of the existing calculation methods were analyzed. The limitations of the existing calculation methods were discussed in terms of the calculation theory and other aspects. Theoretical derivations were performed, and a method for calculating the ultimate flexural capacities of SRC beams with rectangular sections was proposed, and the ultimate flexural capacities of the collected specimens were calculated by using the proposed method. Analysis results show that some deviations are found between the calculated values obtained by the existing calculation methods and the test values. The height value of the compression zone in СИ 3-78 is not appropriate, and the calculation error of this method increases with the increase in concrete strength. The impact of the relative relationship between the neutral axis and the position of the structural steel on the calculation results is not considered in JGJ 138—2016, and limitations exist. YB 9082—2006 and AISC 360-16 do not take into account the interaction between structural steel and concrete or the arrangement of the structural steel. The YE Lie-ping's formulas produce conservative results. The average ratio of the values calculated by the proposed method for the ultimate flexural capacity to the test values of specimens is 0.953, with a variance of 0.015. The calculated values agree well with the test values. The steel ratios of the collected SRC beam specimens range from 1.77% to 5.77%, which is smaller than the reasonable steel ratio range suggested by YB 9082—2006. Therefore, it is necessary to carry out further supplementary tests of specimens with high steel ratios in the future, so as to improve the calculation method for the ultimate flexural capacity of SRC beams with rectangular sections.
