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.
