Abstract Web-post buckling behaviors of fully and partially protected cellular steel beams at elevated temperatures in a fire were investigated through verified finite element models. The partially protected cellular steel beam represented a protected cellular steel beam with the hole edge left unprotected.

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

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.

Numerical and Theoretical Modelling of the Web‐Post Buckling of Stainless Steel Cellular Beams
ce/papers, 2021AbstractCellular steel beams are widely used in modern constructions to achieve long spans and to provide passage for service installations such as ducts and cables. The present paper is concerned with the use of stainless steel in cellular beams. In fact, available design methods to calculate the shear strength of web‐post are applicable only to ...

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 of Web Posts in Perforated Beams
Journal of the Structural Division, 1981The buckling of the web post is investigated for steel I-beams containing adjacent rectangular web openings, and a method is presented for determining the buckling moment. An expression is derived for the effective buckling length of a web post, and its validity is demonstrated by means of tests on scale models.

Engineering Journal, 2017
The research presented in this paper addresses the need for a design method to estimate the nominal capacity of castellated beams against concentrated loads. The limit state investigated is that of web post buckling due to compression loads. The purpose of the paper is twofold: (1) to investigate the limit state of web post buckling due to compression ...

Stiffened shear webs: post-buckling failure of stiffeners of less than critical rigidity
The Aeronautical Journal, 1979The buckling coefficient for a conventional shear web, reinforced by a series of equally-spaced transverse stiffeners, is practically independent of the flexural rigidity of the stiffeners provided this exceeds a certain critical value. The stiffeners then provide conditions close to simple-support (if they are of negligible torsional stiffness).

Numerical simulation of shear-induced web-post buckling in castellated and cellular beams
Alveolar beams are steel structural members with regular web openings, the most common configurations being hexagonal (castellated) and circular (cellular). Due to the presence of sequential openings, these members, when subjected to shear force, may experience shear web post buckling (WPB), the phenomenon investigated in this study.Klaus Hubert Alves Rodrigues +3 more
