Abstract

This paper selects a project as an example to use finite element software to calculate and analyze three different cable and beam construction sequences, and to observe the difference between the cable tension and the main beam stress caused by different familiarities in different cable constructions. Analyze. After the results of this study, it is confirmed that the lag-tensioned zipper method accelerates the construction speed but reduces the upper edge stress reserve and the cable tension of the box girder, which confirms the construction sequence and stress and cable force of the cable area. There is a correlation between them.
