“…With the continuous development of science and technology, wide flange steel has emerged. Honeycombed steel beams have begun to be widely used in bridges, factories, crane bridges and other projects, which can reduce the use of steel by 45%, and the cross-sectional height of honeycombed beams after opening can be increased by 1.2-1.7 (Raut et al, 2020). As the height of cross section increased, the moment of inertia and resistance of cross section increased, so the stiffness and strength of beams could be improved (Ji et al, 2021a).…”

Honeycombed beams are widely used because they are conducive to the layout of pipelines and circuits, and the traditional honeycombed beams are generally H-shaped steel beams and concrete-encased upper flange composite beams. In this paper, a composite beam with concrete-filled steel tube as both upper and lower flanges and steel plate with circular openings as web is proposed. The effective constraint of steel tube on concrete strengthens the deformation ability of concrete. In order to study the flexural behavior of composite beams with concrete filled steel tube flanges and honeycombed steel webs (SHC), 25 simply-supported SHC beams were designed to carry out the four-point bending load simulation analysis. By reasonable modeling method. The main parameters of SHC concluding the compression strength of concrete (fck), yield strength of steel (fyfk), height-to-span ratio (H/L), ratio of space to height of web (s/hw), thickness of steel tube flange (t1), thickness of web (t2) and ratio of hole to height of web (a/hw) were discussed, and the whole loading process of the beam was analyzed. The results showed that the SHC specimens could be divided into elastic stage, elastic-plastic stage and plastic stage under four-point bending load. Steel tube in the tensile zone yielded firstly before specimens failed, and the failure mode of the specimens was that the concrete at the loading point was crushed. Though the steel tube in lower flange at the support, loading point and mid-span yielded, the web did not buckle. SHC could meet the requirements of Chinese code in the normal use stage, and the cross-section deformation basically conformed to the plane assumption. Finally, based on the unified strength theory, a prediction formula of ultimate bending moment is established, which is in good agreement with experiment and can lay the foundation for the popularization and application of this kind of beams.

“…In the present study, the finite element analysis is carried out for solid beam and castellated beams of depth 150 mm, 225 mm to determine their maximum load-carrying capacity, deflection, and stress. [6][7][8][9] A 3-D finite element (FE) model is established to replicate the behaviour of solid and CBs having the cross-section of I-shaped with FE packages ANSYS 16.0 and19.2.…”

Using ANSYS WORKBENCH 16.0 for Finite Element Analysis, this dissertation examines various failure patterns and the impact of web openings on different structural characteristics. The current study examines the static evaluation of single and double solid web, single and double web castellated beams as well as the nonlinear time historical analysis of these beams. singleIn this study, steel beams with , double and single solid webs, double and single web castellated beams are designed and studied using finite element analysis. This shows that castellated beams have a higher load carrying capability than their parent beam sections up to the serviceability limit (i.e. solid beams) Lateral torsional buckling is the primary mode of failure, and it is mitigated in double solid web and double web castellated beams as compared to single solid and single web castellated beams.
