| Abstract: | This paper makes a comprehensive analysis of segment No. 0 of the continuous box girder bridge, including analysis of 3D stress on the deck, web and bottom plate of the segment. Since shrinkage, temperature and time-dependent effects are considered during the calculation of 3D stress. The result of this paper provides experience for design of the bridge and offers important reference value to segment No. 0 design of the same kind bridge. |
