Cellular beams are usually made of structural steel, but can also be made of other materials. [5] The cellular beam is a structural element that mainly withstands structural load laterally applied to the axis of the beam, and influences the overall performance of steel framed buildings. [6] The type of deflection is mainly done by bending.
A girder (/ ˈ ɡ ɜːr d ər /) is a beam used in construction. [1] 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 ...
I-beams are commonly made of structural steel but may also be formed from aluminium or other materials. A common type of I-beam is the rolled steel joist (RSJ), sometimes incorrectly rendered as reinforced steel joist. British and European standards also specify Universal Beams (UBs) and Universal Columns (UCs).
In this case, the equation governing the beam's deflection can be approximated as: = () where the second derivative of its deflected shape with respect to (being the horizontal position along the length of the beam) is interpreted as its curvature, is the Young's modulus, is the area moment of inertia of the cross-section, and is the internal ...

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.
Steel joists and Joist Girders being erected. In structural engineering , the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points.
The term binding joist is sometimes used to describe beams at floor level running perpendicular to the ridge of a gable roof and joined to the intermediate posts. Joists which land on a binding joist are called bridging joists. [3] [4] A large beam in the ceiling of a room carrying joists is a summer beam. A ceiling joist may be installed flush ...
A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape. These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in length. A plate girder is a girder that has been fabricated by welding plates together to create the desired ...
