A beam with number of regular openings in its web is called castellated beam. Nowadays cost reduction and strength goes hand in hand. In that perspective this paper presents an overview of recent research on castellated beam for circular and hexagonal web openings. The castellated beams are well accepted for industrial buildings, power plant and multi storey buildings. Castellated beam gain its advantage due to its increased depth of section without any additional weight. The research paper gives details about the load vs. Deflection comparison for castellated beam for circular & hexagonal opening. The beam is analysed using Finite Element Analysis (ANSYS 18.2).Two point load is applied and stress distribution is studied for circular and hexagonal openings. Through the vierendeel analysis it is clear that stress concentration occurs near the perforations which reduce the shear carrying capacity and stability of the beam. Stress concentrations are more in circular opening than in hexagonal section. Hence hexagonal opening is preferred than circular opening for the further study and it is also found that castellated beams are mostly tend to fail in web buckling.
