“…Few examples were selected from the literature and many of them were interested in changing the shape and diameter of the web openings among these, Deepha et al [1] used lateral stiffeners for castellated structure and it was found that the ultimate strength can be increased up to 54% and the possibility of reducing the stress concentrations by giving fillets on the corners of the web openings. Mehetre and Talikoti [2] investigated the castellated beam with fillet radius and analyzed the beam by the finite element method using ANSYS software, the result shows the suggested beam has less deflection and it was observed that the bending moment bearing capacity of sinusoidal beam is more than the hexagonal opening beam.…”

The use of perforated steel beams (PSBs) has become of great importance due to their wide application in building construction and their beneficial uses as they are economical in terms of cost in addition to their lightweight. The aim of this study is to investigate the static behavior of castellated beams with different web openings. A 3D finite element analysis is performed using ABAQUS, to find out which type of beam gives the best performance under the same distributed load and fixed support condition. Different shapes are used for the web openings and compared with the basic shape of the hexagon, taking the same area into consideration for all shapes. In this paper, a new design model is developed using more than one shape in the web opening. Displacement and stress results are carried out and compared for various cases.

Lateral Distortional Buckling Resistance Predictions of Composite Alveolar Beams: A Review

et al. 2023

View full text Add to dashboard Cite

Few studies have investigated the structural behavior of steel-concrete composite alveolar beams in hogging bending regions. Their resistance can be reached by lateral distortional buckling (LDB), coupling LDB and local failure modes, or limit states of cracking or crushing in the concrete slab. This case is characteristic of continuous or cantilever elements. Another critical issue is that the design and calculation recommendations only address the LDB verification on steel-concrete composite beams without web openings, thus disregarding the interaction between the buckling modes. Furthermore, it is necessary to use adaptations of these formulations for beams with web openings. This review paper aims to evaluate the different approaches for standard code adaptations to verify the LDB resistance of the beams in question and to highlight the investigations that addressed this issue. The addressed adaptations consist of different approaches which determine the cross-section geometric properties in the central region of the openings, the so-called double T section, in the region of the web posts (solid section), and the averages between the solid section and double T section. The accuracy of the formulations in question is verified against experimental results from the literature. Furthermore, discussions and suggestions for further studies are presented.

This study conducts a comprehensive investigation into the influence of web opening shapes on the forced vibration response of castellated steel beams, particularly emphasizing the temporal aspects of the dynamics. These beams are widely employed in practice due to their enhanced structural efficiency and reduced weight, but the incorporation of web openings may potentially impair their shear and bending strength capacities. Three types of web opening shapes are considered. Finite element methodology is employed using ANSYS. The investigation encompasses the forced vibration behavior of castellated steel beams subjected to varying loads. Additionally, the impact of various parameters, including the beam’s geometry, and boundary conditions, on the dynamic behavior of castellated beams are analyzed. The obtained results demonstrate that the web opening shape has significant influence on the vibration amplitudes and oscillation periods of castellated steel beams.
