| Abstract: | This paper makes a comprehensive analysis of segment No. 0 of the continuous box girders bridge, including analyses of 3 D stress on the deck, web and bottom plate of the segment. Since shrinkage, temoerature and time-dependent effects are considered during the calculation of 3D stress, this paper gets accurate secondary stress distribution pattern during the construction and provide a reliable foundation for optimal design of the segment. |
