The average stress in prestressing steel, f ps, may be taken as: f ps This method is applicable to rectangular or flanged sections subjected to flexure about one axis where the Whitney stress block stress distribution specified in S5.7.2.2 is used and for which f pe, the effective prestressing steel stress after losses, is not less than 0.5f pu. In lieu of such analysis a simplified method is presented in S5.7.3.1.1. The stress in prestressing steel at nominal flexural resistance may be determined using stress compatibility analysis.
