| Abstract: | The main bridge of Minpu Second Bridge in Shanghai is a steel truss cable-stayed bridge with single tower and double cable surface, with 40 m span simply box girder of the upper and single pier of lower structure. An initial draft of stud section size and rigidity calculation of stud horizontal line have been introduced in this paper. The author has also discussed the influence of vertical and horizontal earthquake stress to different height studs and the principle of pier foundation when the approach pier under the same earthquake stress. |
