Starting from three macro directions of analysis model establishment, the crack control, and bearing capacity calculation, the detail design process for long-span posted-tensioned bonded prestressed beams is introduced. Some problems, such as degree of the relative height of equivalent compression zone, partial presstressing ratio, rate of tension reinforcing steel bar, and non-prestressed reinforcement area ratio, are discussed and the treatments are put forward. As indicating in the results, for developing a reasonable tension construction scheme, some construction measures for the core areas of tension are suggested, and the design experience could be referred to similar engineering projects., authors=SONG Xiaohong, FAN Qinxin, authorsList=SONG Xiaohong;FAN Qinxin, authorCompany=China Aviation Planning and Construction Development Limited Company,
