“…The adjustment of castellated steel beam separated keep on two types of specimens they were MB1, MB2. MB1 and MB2 was developed as castellated into different opening space 0.25d and 0.15d from research investigation [5], [6], [7], [9]. The variety of opening edge 60o was tried to get the yielding load and the deflection at the centre and under the loading focuses [9].…”

“…Numerous analysts inferred that, beam depth of the section is expanding; deflection of beam is diminishing for every range and for every beams. This shows up as far as possible, castellated bars have more burden conveying limit than its parent segments of beam [6]. The real method of disappointment is lateral torsional buckling and that is decreased in solid beam than castellated beams [7].…”

Castellated beams are made from the conventional I section by the process named as Castellation Process. As of late, broad examination on these castellated steel beams has been directed, including various shapes in web openings. The primary objective of these examination works was to assess and dissect its ideal opening sizes and shapes arrangement. For the most part castellated beam are given hexagonal, round and square formed openings. The finite element investigation is most favored technique for comprehension the flexural strength of castellated beams. In this examination, experimental and numerical displaying approach is utilized for deciding spacing between openings on hexagonal castellated beam. ANSYS software was utilized for the investigation. Opening edge 60o with various opening dispersing 0.15d and 0.25d have beam utilized. Investigation was selected steel beam with and without web openings of ISMB 150 and solid ISMB200 section. Results demonstrated that the castellated bar with hexagonal opening indicated more load carrying capacity and less significant deflection contrasted with solid beam.

“…The accomplished studies indicated that the stress concentration occurs in the corners of the openings leading to initial yielding in the section at the hexagonal opening. Continuing research work was focused on the circular openings by adjusting the angular orientation of the openings to minimize the formation of cracks [8]. The modification of these oval openings for castellated beams certainly requires further study on the stress concentration and failure mechanism due to the presence of the openings.…”

The use of castellated beams has become more popular in the last two decades. The main idea for the use of these types of steel beams is to reduce their self-weight by providing openings in the web of wide flange (WF) or I sections. Numerous research on castellated beams has been conducted, the majority of the studies aimed to optimize the opening size and the shape configuration of the openings. A numerical analysis of castellated beams with oval openings was performed in this study. The sections under investigation had variations in the height-to-length ratios of the beam. The Do to D and b to Do ratios were kept at a constant. The D value was defined as the height of the beam, while Do is the height of the opening, and b is the width of the opening. The numerical analysis was performed by the finite element analysis using the STRAND7 software. The numerical model was further validated to the experimental data. The results showed that the developed finite element model resulted in a very good representation to the actual behavior of the sections.

“…There have been some studies about castellated beam, specifically to investigate (Frans et al, 2017), optimize holes size and space at its web (Cissé et al, 2017), use another shape as an alternative (Tudjono et al, 2017), and so on. Most of them utilize finite element analysis as their method to obtain major parameter like stress and strain (Cissé et al, 2017).…”

Castellated steel beam is a beam with a regular section cut into half with a particular pattern and regrouped with welding to increase its height compared to the original. This structure element has been developed in building constructions since many years ago. However, its uniform section along the span will make the modification no longer effective in cantilever structure, unless it has additional adaptation. Therefore, in this study, it is proposed to use a castellated steel beam with a tapered shape to be applied as cantilever structures. A steel beam with IWF section 150x75x5x7 is the primary sample type in this research. Some variations were made such as openings angle for 450 and 500, openings space for 50 mm, 70 mm, and 90 mm, openings diameter for 50 mm, 75 mm, and 100 mm, and span length for 2 m, 2.5 m, 3 m, and 3.5 m. Two open-source software namely FreeCAD and LisaFEA were used to draw solid 3-dimensional samples and to conduct the numerical analysis to determine stress and deformation respectively. From the result, it is known that the smallest stresses and deformations can be achieved by a different angle of openings, openings space, and diameter for each span length.
