ACI 423.5R-99

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.
