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.

Medieval arch bridges are particularly noted for the ogival, or pointed arch. With the pointed arch the tendency to sag at the crown is less dangerous, and there is less horizontal thrust at the abutments.

A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown meet at an angle at the top of the arch. [1] Also known as a two-centred arch , its form is derived from the intersection of two circles. [ 2 ]

The Karamagara Bridge (Turkish: Karamağara Köprüsü, "Bridge of the Black Cave") is a Byzantine or late Roman bridge in the ancient region of Cappadocia in eastern Turkey, and possibly the earliest known pointed arch bridge.

In bridge: Stone arch bridges ogival arch by concealing the angle at the crown and by starting the curves of the arches vertically in their springings from the piers. This elliptical shape of arch, in which the rise-to-span ratio was as low as 1:7, became known as basket-handled and has…

A flat Gothic (pointed shape) arch in which the rise is less than half the span. Elliptical Arch. In the shape of an ellipse, it differs from a segmental arch in that the curve springs normally from the spring line, then decreases in curvature towards the crown.

2024年12月23日 · London Bridge was designed to have 19 pointed arches, each with a 7.2-metre (24-foot) span and resting on piers 6 metres (20 feet) wide. There were obstructions encountered in building the cofferdams, however, so that the arch spans eventually varied from 4.5 to 10.2 metres (15 to 34 feet).

2023年8月15日 · Karamagara Bridge, in addition to other late Roman and Sassanian variants, largely found in early church construction in Mesopotamia and Syria, demonstrates the pre-Islamic origins of the pointed arch in the architecture of the Near East, which the Muslim occupiers later embraced and expanded on.

To illustrate, think of a bridge with large arches supporting its deck. These arches distribute the weight of the bridge evenly across its length, preventing the bridge from buckling. Pointed arches function similarly in buildings, balancing the load of the roof by channeling forces outward and downward through the arch and into the foundation.
