Steel Arch Bridges

An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. Arch bridges are one of the oldest sorts of bridges and have nice natural strength. They were originally designed of stone or brick however currently are designed of ferroconcrete or more likely of steel which permits arch bridges to be longer with

An arch bridge was extensively used by ancient Romans and is the most popular type of bridge. This bridge is in the shape of an arch, as the name suggests. The loads are carried along the arch’s curve to the support’s end because the curve’s load is not applied directly straight down. The arch bridge carries loads primarily by compression, which exerts on the foundation both vertical and horizontal forces. Arch foundations must therefore prevent both vertical settling and

Whether you need a thrust arch or a tied arch, a single-rib or multi-rib configuration, we fabricate

The tied arch bridge is composed of an arch rib on each side of the roadway, a tie beam associated with each arch rib which takes the thrust from the arches and a deck system supported by the tie beams. The deck system is most commonly composed of a concrete deck supported by longitudinal stringers in turn supported by transverse floor beams. Cable hangers connected between the arch ribs and the tie beams transfer the vertical loads from the tie beams to the arch ribs. Thus

A tied-arch bridge combines features of an arch bridge and a suspension bridge. It uses horizontal thrust from both sides to support an arched structure, as in a regular arch bridge. But instead of an arch supporting the structure from below, the arch rises above the road, and vertical ties descend to increase support of the decking. These are also called bowstring bridges since they look like a bow from the side. This bow uses the tension of its vertical cables, together
