Shear buckling strengths of web-posts in a castellated steel beam with hexagonal web openings
Journal of Constructional Steel Research, 2016Abstract Shear buckling behaviors of web-post in a Castellated Steel Beam (CSB) with hexagonal web openings under vertical shear were investigated using finite element method. Through treating the upper part of the web-post as a free body under horizontal shear force, whose shear buckling strength can be calculated by the thin-plate shear buckling ...

Design procedure for the web-post buckling of steel cellular beams
Journal of Constructional Steel Research, 2018Abstract This research presents a study about the structural behavior of steel cellular beams, focused on the web-post buckling. The main objective of this study is to propose a new formulation to calculate the shear resistance of cellular beams for this phenomenon, based on laboratory tests and numerical analysis.

Web-post buckling of bolted castellated steel beam with octagonal web openings
Journal of Constructional Steel Research, 2020Abstract This paper presented numerical investigations on the behavior of a Bolted Castellated Steel Beam (BCSB) with octagonal web openings. Instead of welding the upper and the lower Tee-sections of a Castellated Steel Beam (CSB) together in the factory, they were connected using high strength bolts at the construction site. Thus, the upper and the

Shear buckling strength of web-posts in castellated steel beams in fire
Engineering Structures, 2020Abstract Most existing formulations for determining shear strength due to web-post buckling by shear (WPBS) in castellated steel beams depend on many variables, are not applicable to fire situation or do not have a normative approach. In order to provide a simpler and more practical formulation, also applicable to the fire situation, this study ...

Buckling and post-buckling of beams with flat webs
Thin-Walled Structures, 2005Post-buckling of a stiffener beam subjected to single shear load was experimentally investigated. The results were analysed using Wagner theory and non-linear finite elements. A new method was proposed to study the postbuckling behaviour. Each panel is divided into two zones.

A Numerical Model for Post-Buckling Analysis of Composite Shear Webs
Mechanics of Advanced Materials and Structures, 2010This paper presents a detailed numerical investigation of the post-buckling behavior of composite shear webs using the finite element method. The numerical analysis accounts for material and geometric non-linearity effects and has been divided into three steps.

Post-Buckling Behavior of Beam Webs in Flexure
Journal of the Structural Division, 1978The results are presented from an experimental study of beams subject to web buckling in a region of pure bending. Two sets of sections were tested, one with the neutral axis at the center of the web and one with 6/10 of the web area in compression.

Post-buckling Strength of Welded Steel I-Girders with Corrugated Webs
International Journal of Steel Structures, 2021Steel I-section-plate girders with corrugated webs have been used worldwide as they provide more stability and light beam features in practical design. It is known from previous investigations that due to having numerous favourable properties, the corrugated-web beams have been used in different areas of structural engineering.
