Abstract: Based on the background of foreign design codes, this paper gave a brief introduction to the design of PPC structural members in the "Code of Design for Reinforced and Prestressed Concrete Highway Bridges" and at the same time, compared these codes with the foreign ones. A brief analysis and discussion on classification of prestresed concrete, on calculation of flexular strength of PPC members and on crack control was carried out. Finally, two practical cross section design methods of PPC bridge with reference to the code were proposed.

摘要： 本文以国外规范为背景,介绍了《公路钢筋混凝土及预应力混凝土桥涵设计规范》中有关部分预应力构件设计的规定,将它与国外规定做了比较。对预应力构件的分类方法,正截面强度计算和裂缝控制等作了简要的分析与讨论。最后提出了按《规范》规定进行部分预应力桥梁截面设计计算的两种可行方法。
