摘　　要：与现浇混凝土相比,预制混凝土结构具有一些显著的优点,如可提高施工速度,减轻工人劳动强度,保证结构质量等。此外,预制预应力混凝土还是减少混凝土变形裂缝,提高结构耐久性的一种途径。介绍了预制预应力混凝土结构在国内外的研究现状,并着重介绍了一种采用通过后张预应力筋将预制构件连接在一起所形成的柔性连接预制框架结构,在对其进行试验研究和理论分析的基础上给出了设计过程中的一些要点。As compared to the cast-in-place concrete structures, the precast concrete ones have some remarkable advantages, such as increasing the constructing speed, lightening the labor intensity of builders, and improving quality of structures, etc. Furthermore, precast concrete structures can afford a selective approach to reduce the deformation cracks of concrete, and thus improve the durability of buildings. The research status of precast concrete structures at home and abroad was indicated. And then a kind of precast concrete frame, whose components are connected by post tensioned prestressing tendons, was introduced in detail. Based on experimental study and theoretical analysis, outline of the design approach of this kind of frame was obtained.
