Arch bridges

The structure of arch bridges fixes and supports the arc-shaped main members in the horizontal direction at both ends, and the bridge consists of a deck arch, a half-through arch, and a through arch, which are named for their positions relative to the girders. In general, arch bridges are structured to guide all forces to the arch ribs and support horizontal reactions on the ground, or have a tied arch structure that makes the girders on the road surface bear the horizontal reactions produced at both supporting points. Tied arch bridges include the Langer, Lohse, and Nielsen types. The applied spans are generally about 50 to 170 meters, and the longest arch bridge in the world is the Shanghai Lupu Bridge, with an effective span of 550 meters. JFE Engineering has manufactured and erected many arch bridges to date.
