Simplified design method for stiffened cellular beams against web‐post buckling
Ce/Papers, 2021AbstractWeb‐post buckling next to Vierendeel effect, is one of the main failure modes for cellular beams. Several solutions are available to avoid web‐post buckling, such as ring stiffener or infill opening. A new cost‐effective solution is to weld a vertical plate stiffener on the web‐post.

Elastic buckling of web-post in cellular beams with various opening shapes
World Journal of Engineering, 2012This paper develops a finite-element model using ANSYS for the buckling analysis of perforated beams and uses it to investigate the effects of slenderness on the moment-gradient factor of simply supported perforated web beams. Web post buckling is studied by using numerical model.

Abstract The shear buckling behavior of the web-post in a castellated steel beam with fillet corner hexagonal web openings is studied using the finite element method. The buckling modes and buckling capacity of the web-post in the castellated beam with fillet corner hexagonal web openings are compared with those having circular and elongated circular

Abstract Buckling behaviors of web-posts in a cellular steel beam at elevated temperatures in a fire were studied using the Finite Element Method (FEM) analysis and available analytical models. The buckling temperatures obtained by the analytical models differed greatly to those obtained from the FEM simulation.

Numerical and analytical study of intermediate web‐post buckling
ce/papers, 2021AbstractIn the case of two adjacent large web openings, the beam may fail by the plastification or the buckling of the intermediate web part known as the web‐post failure. Various analytical approaches have been developed to define the failure load of the intermediate web‐post which can be a key point in the design of beams with web openings.

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.

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.
