Comparative study on the behaviour of castellated beams provided with hexagonal, circular, and diamond-shaped web openings
Since the past decade, the use of castellated steel beam (CSB) is being done extensively for steel structures due to its advantageous properties such as being lightweight, better aesthetics, higher strength-to-weight ratio, easiness in handling, and installation of service pipe through its web openings. CSB is a modified form of steel I-beam that is cut longitudinally along its web into two parts in a specified pattern. The two cut parts are joined back after shifting to form a perforated beam with increased depth and strength. CSBs are classified based on the shapes of openings provided in the web portion. Hexagonal, circular, diamond, sinusoidal, octagonal, etc. are some of the most commonly adopted opening shapes. Research studies have indicated that the structural behavior of CSB varies with the provision of differently shaped web openings. In this paper, the behavior of CSBs provided with different shapes of openings viz. hexagonal, circular and diamond has been studied considering two-point loading using Abaqus software for determining the load-carrying capacity and deflection values. Results indicate that the CSB with diamond-shaped openings shows an average increase of 13.72% in load-carrying capacity and an average reduction of 36.14% in deflection when compared with the corresponding values of CSBs provided with hexagonal and circular openings. The study concludes that the CSB with diamond-shaped openings performs better in comparison with the CSB possessing hexagonal and circular openings.
