Abstract
Cellular Beams with Closely Spaced Web Openings – A Review of Analytical Calculation Models for Web-Post Buckling
Highlights
Cellular beams are being used more often in modern buildings and industrial structures
The main objective of this paper is present a summary of research on web post buckling (WPB) in cellular beams in light of the available analytical computational methods for determining WPB resistance based on the analogy to compression member buckling
Calculated load capacity for each of the beams are presented in Figure 7, distinguishing between the individual methods described in this article [15, 30, 32, 33, 23, 34, 35]
Summary
Cellular beams are being used more often in modern buildings and industrial structures. The static behaviour theory and mechanisms of cellular beams failure refer to the so-called Vierendeel girder developed as a new type of metal bridge girder at the end of the 19th century by a Belgian engineer, Professor Arthur Vierendeel [1]. A perforated beam is fabricated, for example, by cutting an I-section along a broken line around the centre line of the web, repositioning the resulting T-sections and re-welding the two halves in the place of the so-called posts. A post is understood to be a solid web area between the Advances in Science and Technology Research Journal 2022, 16(1), 1–230 openings. The idea behind this solution is to obtain a section that is about 30–60% deeper that the parent section. Its bending stiffness increases about the stronger axis without increasing the amount of steel used
