Assessment of web post buckling resistance in steel-concrete composite cellular beams

Thin-Walled Structures, 2021
Abstract This paper aims to investigate the ultimate strength of steel-concrete composite cellular beams, considering the web post buckling. The numerical model is calibrated via experimental tests consolidated in the literature by geometrical non-linear analyses. Asymmetric and symmetric sections are investigated.

Design procedure for the web-post buckling of steel cellular beams

Journal of Constructional Steel Research, 2018
Abstract 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.

Simplified design method for stiffened cellular beams against web‐post buckling

Ce/Papers, 2021
AbstractWeb‐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.

Web-post buckling of bolted castellated steel beam with octagonal web openings

Journal of Constructional Steel Research, 2020
Abstract 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

The evaluation of the previous models used to study the web post-buckling

International Journal of Steel Structures, 2017
The 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 ...

Novel design equations for shear strength of local web-post buckling in cellular beams

Thin-Walled Structures, 2014
To 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 ...

Shear buckling strengths of web-posts in a castellated steel beam with hexagonal web openings

Journal of Constructional Steel Research, 2016
Abstract 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 ...

Practical method for calculating the buckling temperature of the web-post in a cellular steel beam in fire

Thin-Walled Structures, 2014
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.

Elastic buckling of web-post in cellular beams with various opening shapes

World Journal of Engineering, 2012
This 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.
