The paper has also calculated the cracking moment of reinforced concrete sections corresponding to different reinforcement ratios, the calculation results have showed that: (1) the cracking moment increases linearly as a function of tensile reinforcement ratio and of compressive reinforcement ratio; (2) the tensile reinforcement ratio has a great influence on the cracking moment while the influence of compressive reinforcement ratio is insignificant; (3) the approximate method presented in TCVN 5574 – 2018 significantly underestimates the cracking moment of the section, especially in the case of high tensile reinforcement ratio.
