Optimisation of Novel Elliptically-Based Web Opening Shapes of Perforated Steel Beams [PDF]
, 2012 A new study was carried out and presented herein, on the optimisation of novel elliptically-based web opening shapes which enhance the structural behaviour of the perforated beams as well as lead to economic design in terms of both manufacture and usage.

Journal of Civil Engineering and Management, 2008 There are many methods to calculate castellated steel beams; however, neither of these methods determines the rational cross‐section selection. Selecting the rational cross‐section induces a significant reduction in the quantity of steel. A new algorithm

Structural Behaviour of Castellated Beam: A Review
International Journal of Advanced Research in Science, Communication and Technology, 2023 The use of castellated beams has gained popularity due to their excellent performance in terms of strength, stiffness, and economy. Castellated beams are fabricated by cutting I-sections or H-sections along the web in the desired shape and re-joining the two halves on one another through welding in order to improve the beam's overall depth. Most often,

The Effects of Reduced Beam Section on Castellated Beam [PDF]
MATEC Web of Conferences, 2017 This paper presents reduced beam section (RBS) technique on castellated beam. Aim of this study is to ensure the plastic moment reach far from column face without significant of strength decreasing. Four models of castellated beam with various types of RBS and one model without RBS have been considered.

Prediction of the castellated beams deflections
Vestnik MGSU, 2022 Introduction. Existence of openings in webs of beams reduce their shear rigidity and increase deflections compare with beams of the same dimensions with solid web. Investigation of the castellated beam’s deflections is important, because one of main demands to beams of engineering structures is guarantee of necessary rigidity, i.е. restriction of ratio
