A schematic representation of the production process of a castellated beam. A castellated beam is a beam style where an I-beam is subjected to a longitudinal cut along its web following a specific pattern. The purpose is to divide and reassemble the beam with a deeper web by taking advantage of the cutting pattern. [1]
Cellular beam is a further development of the traditional castellated beam. [1] The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction .

The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape ...
where I is the moment of inertia of the beam cross-section and c is the distance of the top of the beam from the neutral axis (see beam theory for more details). For a beam of cross-sectional area a and height h , the ideal cross-section would have half the area at a distance h / 2 above the cross-section and the other half at a ...

In pre-engineered buildings, the I beams used are usually formed by welding together steel plates to form the I section. The I beams are then field-assembled (e.g. bolted connections) to form the entire frame of the pre-engineered building. Some manufacturers taper the framing members (varying in web depth) according to the local loading effects.
Konstantinos Daniel Tsavdaridis (Greek: Κωνσταντίνος Δανιήλ Τσαβδαρίδης; Born in Thessaloniki, Greece) is a professor at the School of Civil Engineering of the University of Leeds, known for his work on lightweight steel and steel-concrete composite structures and particularly for the design of novel perforated beams and tall buildings.
