INSUBCONTINENT EXCLUSIVE:
stone masonry, which is an appropriate material for sustaining compressive forces
An arch bridge carries loads primarily by compression, which experts on the foundation both vertical and horizontal forces
Arch foundations must therefore prevent both vertical settling and horizontal sliding
Despite the more complicated foundation design, the structure itself normally requires less material than a beam bridge of the same
span.Arch bridges can be classified into deck arch bridges (featuring arches below the deck) and through arch bridges (those with arches
above the deck, generally tied arches)
In all arch bridges, structural difficulty can be found in the minimization of the misalignment of the arch axis and the line of thrust, as
well as sufficient bending and buckling resistance
General design recommendations focus principally on the arch-to-span ratio, the arch and deck slenderness, and the number of hangers or
