- Synopsis
- Tohoku-Shinkansen Sannaimaruyama Bridge is longest span Shinkansen Bridge. In this paper, new method of stay-cable fixed system that is Single duct structure in saddle system to main-tower are proposed. Stay cable is fixed by adhesion resistance of steel-pipe and pull-out resistance of anchor-flange. Loading tests of members, which assumed large-scale earthquake, were conducted to verify the method. As the results, it was verified that Single duct structure in saddle system function sufficiently as stay-cable fixed system.
