    en.wikipedia.org/wiki/Box_girder

    A box girder or tubular girder (or box beam) is a girder that forms an enclosed tube with multiple walls, as opposed to an Ɪ-or H-beam. Originally constructed of wrought iron joined by riveting , they are now made of rolled or welded steel, aluminium extrusions or prestressed concrete .

  4. Composite construction - Wikipedia

    en.wikipedia.org/wiki/Composite_construction

    A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Additionally, composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load ...

  5. Orthotropic deck - Wikipedia

    en.wikipedia.org/wiki/Orthotropic_deck

    The same structural effects are also true of the concrete slab in a composite girder bridge, but the steel orthotropic deck is considerably lighter, and therefore allows longer span bridges to be more efficiently designed. Resistance to use of an orthotropic deck relates mainly to its cost of fabrication, due to the amount of welding involved.

  6. Structural material - Wikipedia

    en.wikipedia.org/wiki/Structural_material

    Timber is the oldest of structural materials, and though mainly supplanted by steel, masonry and concrete, it is still used in a significant number of buildings. The properties of timber are non-linear and very variable, depending on the quality, treatment of wood, and type of wood supplied.
