Composite Deck (Beam) Arch Bridges

Abstract

Arch bridges are one of the oldest bridges in the history of humanity and are characterized by beautiful modeling and long spanning compared with ordinary beam bridges. Arch bridges are thrust structures. Under the vertical loads, the arch foot produces not only vertical reaction forces but also a horizontal thrust so that the axial pressure is generated in the arch, the bending moment of the arch is minimized, and the material strength of the main arch section is fully used. As with other bridge types, the development of arch bridges has always been subject to the constraints of mechanics, materials, science, and construction technology. With the progression of science and materials, the development of arch bridges has gone through various stages, including stone arch bridges, steel arch bridges, reinforced concrete arch bridges, and concrete-filled steel tubular arch bridges.
