Bridges

Composite deck slab bridges

River bridges

River bridges are original steel-concrete composite deck slab bridges of JFE Engineering that use T-shaped steels with a filling knot-like projection on the outside surface of the flange as a shear connector. Since shear connectors such as studs are no longer required, this structure makes it possible to construct bridges with low girder height that cannot be constructed with other structures. Since this bridge structure was first practically applied, we have constructed more than 420 river bridges to date.
Simple girder bridges are compatible with spans of up to about 40 meters and skew angles of more than 45 degrees, and continuous girder bridges can also be constructed. As a result, the application of our river bridge structure is expanding significantly to road bridges over rivers, overbridges, etc.
