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, and partially into a vertical load on the arch supports.
The through arch bridge usually consists of two ribs, [5] although there are examples like the Hulme Arch Bridge of through arches with a single rib. When the two arches are built in parallel planes, the structure is a parallel rib arch bridge. When the two arch ribs lean together and shorten the distance between the arches near the top, the ...
The Ponte Vecchio (Italian pronunciation: [ˈponte ˈvɛkkjo]; [1] "Old Bridge") [2] is a medieval stone closed-spandrel segmental arch bridge over the Arno, in Florence, Italy.The only bridge in Florence spared from destruction during World War II, it is noted for the shops built along it; building shops on such bridges was once a common practice.
In the 3rd century, segmental arch bridges, or flat arch bridges, emerged. One of the earliest examples of this type of bridge is the Limyra Bridge, [15] situated near Limyra in present-day Turkey. It is 360 meters in length and comprises 26 segmental arches and two semi-circular arches. [16]

A fixed arch bridge, that is one without hinges, exerts a bending moment at the abutments and stresses caused by change of temperature or shrinkage of concrete have to be taken up by the arch. A two-hinged arch has a hinge at the base of each arch (the springing point), while a three-hinged arch has a third hinge at the crown of the arch. [3]
