    The standard depth at the bearing ends has been established at 7 + 1 ⁄ 2 inches (190 mm) for all Joist Girders. Joist Girders are usually attached to the columns by bolting with two 3 ⁄ 4 inch (19 mm) diameter A325 bolts. [1]

    en.wikipedia.org/wiki/Hollow_structural_section

    In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...

  4. Box girder - Wikipedia

    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 .

  5. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    In Canada, steel I-beams are now commonly specified using the depth and weight of the beam in metric terms. For example, a "W250x33" beam is approximately 250 millimetres (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the other flange) and weighs approximately 33 kg/m (22 lb/ft; 67 lb/yd).

    A double floor is a floor framed with joists supported by larger timbers.. In traditional timber framing there may be a single set of joists which carry both a floor and ceiling called a single floor (single joist floor, single framed floor) or two sets of joists, one carrying the floor and another carrying the ceiling called a double floor (double framed floor).

    Steel never turns into a liquid below this temperature. Pure Iron ('Steel' with 0% Carbon) starts to melt at 1,492 °C (2,718 °F), and is completely liquid upon reaching 1,539 °C (2,802 °F). Steel with 2.1% Carbon by weight begins melting at 1,130 °C (2,070 °F), and is completely molten upon reaching 1,315 °C (2,399 °F).

  8. Cross bracing - Wikipedia

    en.wikipedia.org/wiki/Cross_bracing

    In steel construction, steel cables may be used due to their great resistance to tension (although they cannot take any load in compression). The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a ...

  9. ASTM A500 - Wikipedia

    en.wikipedia.org/wiki/ASTM_A500

    ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections, but the more stringent CSA G40.21 is preferred in Canada.
