Comprehensive Review on the Studies on Castellated Beam

The numerous studies on castellated beams, a kind of steel beam that is frequently employed in structural engineering due to its exceptional strength-to-weight ratio and aesthetic appeal, are examined in this thorough literature review. Standard Ibeams are split and reassembled to form web apertures in castellated beams, which preserve structural strength while using less material. Important subjects covered in the paper include the structural performance of castellated beams under bending, shearing, and axial loads, among other loading situations. Important design considerations are also covered, such as how hole size, shape, and placement affect beam efficiency. Research on castellated beams' buckling properties, fatigue durability, and failure modes is reviewed, as are methods for improving their design to strike a compromise between cost and performance. Furthermore, the paper highlights advancements in computational methods, particularly the use of software for finite element analysis (FEA), such as Abaqus, which has emerged as a crucial tool for simulating the complex behaviours of castellated beams. The significance of experimental studies in confirming analytical models and expanding our understanding of castellated beam behavior in real-world scenarios is also included in the review. In order to keep up with the latest developments in castellated beam design and technology, engineers and researchers can benefit greatly from consulting this survey of the literature.
