Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...

The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold.
The other (the suspended span) begins underneath the anchor span, and has its far end resting on the next pier. The beams have holes directly above each other. The two holes are connected using hangers, a pair of connecting plates sandwiching the bridge girders. A pair of large steel pins through the plates and girder webbing provide the hinges ...
The old Britannia Bridge with train track inside the box-girder tunnel Section of the original tubular Britannia Bridge The patent curved and tapered box girder jib of a Fairbairn steam crane A box girder or tubular girder (or box beam ) is a girder that forms an enclosed tube with multiple walls, as opposed to an Ɪ- or H-beam .
Gien Bridge (Loiret, France) – Masonry piers, protected downstream here by backwaters. In masonry bridge piers, there is a resistant part and a filling part: [ 6 ] The periphery of the shafts over a certain thickness constitutes the resistant part, made of dressed stones in the angles and squared or even rough stones.
