Pre-buckling and post-buckling failure at web-flange junction of pultruded GFRP beams
Materials and Structures, 2012Separation at the web-flange junction is a common failure mode of pultruded glass fiber-reinforced (GFRP) beams subjected to bending. The causes of this separation appear to depend on the presence of lateral supports to prevent lateral buckling. To clarify the driving mechanisms, four-point bending experiments were carried out on pultruded GFRP girders.

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

The evaluation of the previous models used to study the web post-buckling
International Journal of Steel Structures, 2017The number of suggested and modified theories for web post-buckling behavior shows that this is one of the topics receiving much attention in civil engineering. However, the controversy related to the elusive behavior of web post-buckling is going on. The present study using an updated data set from 27 previous experimental shear tests and the current ...

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 ...

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.

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.

Web Yielding, Crippling, and Lateral Buckling under Post Loading
Journal of Structural Engineering, 2007Unstiffened, unbraced steel beams used in bridge falsework are subjected to patch loads from timber or steel posts. This paper investigates the critical web limit states in these types of beams experimentally and through finite-element analysis. Existing equations were appropriate for calculating the web yielding and crippling capacity, as observed in ...

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.

An experimental and numerical analysis for the post-buckling behavior of composite shear webs
Composite Structures, 2011This paper presents a detailed experimental and numerical investigation on the structural behavior of stiffened composite panels subjected to in-plane shear loads. The experimental work includes the development of a test device for post-buckling analyses of laminated panels subjected to shear loads.
