  1. Bridges

  2. Bridges • A bridge is a structure built to span a gorge, valley, road, railroad track, river, body of water, or any other physical obstacle. • A bridge is designed for trains, pedestrian or road traffic, a pipeline or waterway for water transport or barge traffic. • An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height. • A road-rail bridge carries both road and rail traffic. • A bridge's structural efficiency may be considered to be the ratio of load carried to bridge mass, given a specific set of material types. • A bridge's economic efficiency will be site and traffic dependent, the ratio of savings by having a bridge (instead of, for example, a ferry, or a longer road route) compared to its cost.

  3. Classification of Bridges • Beam bridges • Cantilever bridges • Arch bridges • Suspension bridges • Cable-stayed bridges • Truss bridges Based on Action

  4. Classification of Bridges • Concrete Bridge • Steel Bridge • Timber Bridge • Composite Bridge Based on Material used

  5. Classification of Bridges Based on purpose • Road Bridge • Rail Bridge • Rail & Road Bridge • Pedestrian Bridge • Aqueduct

  6. Classification of Bridges Based on type of Support • Simply Supported Bridges • Continuous Bridges • Fixed Bridges • Cantilever Bridges

  7. Components of Bridge • Caisson/Raft Foundation • Bridge Pier • Bearing • Deck Slab • Roadway • Railing • Abutment 6 4 3 2 7 7 1 1 1
