13/10/2022 · noun. : a horizontal main structural member (as in a building or bridge) that supports vertical loads and that consists of a single piece or of more than one piece bound together.

A girder (/ ˈ ɡ ɜːr d ər /) is a support beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges.

noun a large beam, as of steel, reinforced concrete, or timber, for supporting masonry, joists, purlins, etc. a principal beam of wood, steel, etc., supporting the ends of joists. QUIZ Question …

A girder is any of the many beams used in buildings and bridges that provide support and actually hold them up. If you've ever seen a building going up, you know the first thing they do is put up a steel or wood skeleton that will eventually take the weight of the roof, the siding, the floors, and all the rooms inside.

Girder noun a main beam; a stright, horizontal beam to span an opening or carry weight, such as ends of floor beams, etc.; hence, a framed or built-up member discharging the same office, technically called a compound girder. See Illusts. of Frame, and Doubleframed floor, under Double Etymology: [From Gird to sneer at.]

What Does Girder Mean? Girders are main horizontal support members of structures, such as drill rigs, and support other structural members, like beams. They are also known as beams, but all beams are not girders. They usually have a cross-section like an "I", with two flanges and a web. They also come in other shapes such as box or "Z".

Basics of Girder: Girder is the type of beam that supports other small beams, thus acting as the main horizontal supports of a structure. Unlike beams, the girder is designed to support significant concentric loads such as columns or beam reactions. The load-carrying capacity of the girder is much higher than that of the beam.

A steel girder is a large horizontal beam that supports a structure. Fabricators of structural steel produce many sorts of beams based on their length, width, and weight. In comparison to girders, beams are typically smaller. Girders can support a lot of weight. Steel is extremely durable, thus they can handle heavy loads.
