Bridge Types - INI
Bridge types are classified by structural form into beam/girder bridges, truss bridges, arch bridges, rigid frame bridges, cable-stayed bridges, and suspension bridges. Each structure differs in mechanical characteristics, applicable span length, construction cost, and aesthetics, with the optimal type selected based on construction conditions and purpose. Beam bridges are the most basic and used in approximately 80% of bridges, while suspension and cable-stayed bridges are suitable for long-span bridges.
