摘　　要：利用综合内力法原理 ,推导了预应力混凝土结构正截面极限承载力计算公式 ,这些公式采用预应力作用下的综合内力 ,考虑次轴力和次弯矩的影响 ,可用于正截面受弯承载力、偏心受压承载力和偏心受力各类结构的承载力计算。本文公式简捷 。Utilizing the basic theory of the method of resultant internal forces,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.They are able to apply to calculate the normal section flexural load\|bearing capacity of flexural member,compressive loading\|bearing capacity of eccentric compression member and tensile load\|bearing capacity of eccentric tension member.

关 键 词：预应力混凝土结构 极限承载力 结构设计
