| Abstract: | This paper makes a comprehensive analysis about the zero segment and the main contents are as follows: Analysis of 3D stress on the deck, web and bottom pkte of the zero segment. Since shrinkage, temperature and tune-dependent 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. |
