By using the principle of integrated internal force method proposed in this paper, the influence of secondary and secondary moment can be considered. The comprehensive internal force under prestressing force is used to deduce the practical design formulas for crack resistance of prestressed concrete structures, insufficient. This formula is simple and convenient for practical engineering applications, can be suitable for various types of prestressed concrete structure cracking design checking.
