Cellular Beams with Closely Spaced Web Openings – A Review of Analytical Calculation Models for Web-Post Buckling

Abstract: This paper is devoted to cellular beams manufactured by fl ame cutting and welding of hot rolled I-sections. The infl uence of fabrication proces ses on the size of geometric and material imperfections was considered. Static performance was characterised, as were the failure modes, with particular emphasis on the Vierendeel mechanism and web-post buckling. As the literature review shows, a local loss of web post stability is a frequent failure mode of cellular beam with closely spaced web openings. The main ob… Show more
