Section bending analysis. As1 represents the total area of the tension bars and As2 is the total area of the compression bars. Moreover, ε represents the section strain which is a function of the ordinate. Furthermore, T1, T2, and P1, respectively, represents the resultant force of the first-row tension bars, that of the second-row tension bars, and that of the compressed steel bars. What is more, Mu is the bending moment of section. a T-shaped section. b Section strain distribution. c Section stress distribution
