本文提出了后张预应力在混凝土结构中产生的当量荷载的计算方法。推导了等代预应力对结构作用的等效荷载和当量荷载，揭示了等效荷载与当量荷载的区别与联系。对于沿连续布置预应力筋范围内构件截面有变化的结构，用当量荷载等代预应力效应，计算方法简捷，计算结果正确。
This paper proposes a calculation method for equivalent loads generated by post-tensioned prestressed concrete structures. The equivalent loads and equivalent loads acting on the structure with equal prestress are deduced, revealing the differences and relations between equivalent loads and equivalent loads. For the structure where the cross-section of the internal members along the pre-stressed tendons is continuously arranged, the calculation method is simple and the calculation result is correct with the equivalent preload effect such as equivalent load.
