Novel design equations for shear strength of local web-post buckling in cellular beams
Thin-Walled Structures, 2014To complement available design methods, this study develops a practical and economical approach to estimate shear strength of non-composite symmetric and asymmetric cellular beams, based on failure by local web-post buckling. Influence of geometric web-post parameters on the buckling strength and mechanism, such as section size, opening depth ratio ...

Fatigue resistance of post-buckled slender trapezoidal corrugated webs in girders with stiff flanges
Engineering Structures, 2019Abstract Slender trapezoidal corrugated web does generally possess notable post-buckling capacity with certain reserve of shear resistance. Repeated secondary bending stresses due to post-buckling at the boundaries of the subpanel of the trapezoidal corrugated web, however, may result in potential local fatigue failure.

Tension Wrinkling and Fluting in Heatset Web Offset Printing Process – Post-buckling Analyses
Trans. of the XIIIth Fund. Res. Symp. Cambridge, 2005, 2005Geometrically non-linear, large scale post-buckling analyses were carried out to investigate the influence of different parameters on residual waviness (fluting) after printing in a heat set web offset printing press. Mixed implicit-explicit finite element techniques were used in the analyses.

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 ...

Comparison on Calculation Method for Post-Buckling Strength of Thin-Webbed I-Shape Member
Applied Mechanics and Materials, 2014The thin-webbed I-shaped members are used as the basic members for beams and columns of steel buildings in order to increase utilization ratio of steel. The local buckling can occur for these members because of the large width-thickness ratio and these members have a substantial post-buckling strength which can be used.

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
