摘　　要：利用本文提出的综合内力法原理 ,可考虑次轴力和次弯矩的影响 ,采用预应力作用下的综合内力 ,推导出各类预应力混凝土结构抗裂实用设计公式 ,补充了现有规范的不足。本文公式简捷 ,便于实际工程应用 ,可适合各类预应力混凝土结构的抗裂设计验算。Utilizing the basic theory of the method of resultant internal forces presented in this article,the practical calculating formulas for the crack resistance capacity of normal section are deduced.These formulas consider the influence of the secondary axial force and secondary moment and use the resultant internal force directly,so that defaults in the current codes are complemented.They are able to apply to calculate the crack resistance capacity of normal section of various PRC structures for its practice and convenience. \[
