Parametric Study of Castellated Steel Beams

In this study, a detailed parametric investigation of the castellated beams (CBs) is done by analytical and experimental methods. The usage of CBs or perforated web beams has become very widespread nowadays as a result of its valuable structural applications. A lot of research work has been supported for improving sizes of castellated steel beams (CSBs) and henceforth there is a requirement to optimize the steel beams with varying depths of hexagonal opening. The objective of this research is to do a comparative study of the parent beam that is I-beam and CBs with changing depth. The study is a performance-based investigation on bending strength, deflection, lateral-torsional buckling moment, bending compressive stress, and shear capacity of I-beam and also investigates the moment of resistance, deflection of CBs with standard hexagonal shape of the opening. These are done on an analytical and experimental basis.
