In recent years, due to its beneficial structural applications, castellated steel beam (CSB) is widely used in the construction industry. CSBs are beams with openings of different shapes in their web. CSB is fabricated from steel I-beams by cutting lengthwise along their web to form two separate parts which are then put together after shifting to create a beam with openings and increased depth. CSBs are fabricated with different shapes of openings like hexagonal, circular, diamond, octagonal, etc. However, such openings result in the failure of CSB, reducing the load-carrying capacity (LCC), and hence, its strengthening becomes essential. In this paper, the behavior of CSBs with hexagonal, circular, and diamond openings is analyzed using Abaqus software considering the provision of mild steel (MS), carbon fiber-reinforced polymer (CFRP), and basalt fiber-reinforced polymer (BFRP) materials as stiffeners around the openings under two-point loading. Results of analysis for LCC and deflection are validated by experimentation. Results imply that the LCC and deflection of CSB consisting of diamond openings provided with MS stiffeners increase by 11.52% and reduce by 24.07%, respectively, when compared with the average load-carrying capacities (LCCs) and deflection values of CSBs consisting hexagonal and circular openings. Further, LCCs and deflections of CSBs consisting of diamond openings with CFRP and BFRP stiffeners are found to be less by 7.6% compared with the corresponding values of CSBs with MS stiffeners. The study concludes that using FRP for stiffeners can be a better alternative to replace MS stiffeners, as it contributes in reducing the weight.
