Abstract

Castellated beams have become increasingly popular in structural applications due to their enhanced load-carrying capacity and efficient use of material. These beams are created by cutting a zigzag pattern into the web of a hot-rolled steel (HRS) I-section and rejoining the cut portions, effectively increasing the beam's depth. The shape of the openings in the web can vary, with common configurations including sinusoidal, hexagonal, octagonal, diamond, and circular patterns. The increase in depth improves the beam's ability to carry loads, but it also introduces potential failure modes such as lateral-torsional buckling, shear issues, and flexural instability. To mitigate these risks, research has highlighted the importance of incorporating stiffeners into the web portion of the beam. Stiffeners, available in various forms, serve to reduce deflection, enhance strength, and minimize stress concentrations around the openings. Their strategic placement significantly improves the beam's overall structural performance and durability, making castellated beams a more reliable and efficient choice for modern construction.
