Abstract
PSC box girder bridges usually have a lot of tendons, and the difference of the bursting forces lies in the prestressing order of the tendons. As a result of the lack of studies on the prestressing order for the bridges, the order depends on the designer's intuition and experiences. In this paper, with investigation into various methods determining the bursting force of the anchorage, reasonable prestressing order is determined by analysis of PSC beam bridge and PSC box girder bridge with most suitable method. It may be stated that this study would be useful for determining the reasonable prestressing order of tendons for the PSC box girder bridges.
