部分预应力混凝土结构使用预应力钢筋或预应力和非预应力钢筋的组合。部分预应力混凝土介于常规钢筋混凝土和完全预应力混凝土的极限情况之间，在工作荷载下不允许弯曲张力。当在使用荷载下允许弯曲拉伸应力时，预应力构件在历史上被称为部分预应力构件。本报告概述了部分预应力，涵盖了许多主题。

Partially prestressed concrete construction uses prestressed reinforcement or a combination of prestressed and nonprestressed reinforcement. Partially prestressed concrete falls between the limiting cases of conventionally reinforced concrete and fully prestressed concrete, which allows no flexural tension under service loads. When flexural tensile stresses are allowed under service loads, the prestressed members have historically been called partially prestressed. This report is presented as an overview of partial prestressing and covers numerous topics.
