摘　　要：基于预应力混凝土构件在等效荷载作用下混凝土截面内力的分析,给出综合内力、主内力和次内力的物理意义及简捷计算方法,从而方便了工程设计计算,有利于预应力混凝土结构的推广与应用。Based on the analysis of internal forces for prestressed concrete structures caused by equivalent load, the definition of resultant internal forces and first internal forces and secondary internal forces are presented and convenient caculation, so as to bring convenient for engineering designing and calculating. The method, will benefit in popularization of application of prestressed reinforced concrete structures.

关 键 词：预应力混凝土结构 预应力 次内力 综合内力
