Thin-Walled Structures, 2022 In this paper, the influence of the web-post geometric parameters on the shear buckling resistance of perforated steel beams with previously proposed novel non-standard elliptically-based web openings is investigated. An economical and practical approach to estimate the web-post buckling resistance in accordance with EUROCODE 3 and the buckling ...

Web-post buckling prediction resistance of steel beams with elliptically-based web openings using Artificial Neural Networks (ANN) [PDF]
Thin-Walled Structures, 2022 This paper aims to propose an Artificial Neural Network (ANN) model that predicts accurately web-post buckling resistance and failure mode of steel beams with elliptically-based openings. A total of 4,344 and 5,400 geometrical models, were developed by finite element method (FEM) and used to train, validate and test the ANN model for the web-post ...

Post buckling resistance reserve of corrugated girders with support stiffeners [PDF]
Archives of Civil Engineering, 2022 The analysis of web-corrugated and trapezoidal profiled web girders focuses on the description of buckling resistance, possibly the ultimate resistance neglecting the post-buckling resistance reserve of girders.

Slender metal web stability analysis: Impact of initial imperfection on the mode of buckling [PDF]
MATEC Web of Conferences, 2020 The post buckling of a rectangular slender web in compression has been analyzed. Shapes of a buckling area obtained from the nonlinear analysis have been compared with buckling modes from the linearized problem for various aspect ratios.

Experimental study of the behaviour and failure modes of tapered castellated steel beams
Open Engineering, 2022 This article discusses the experimental testing of tapered castellated beams (TCBs) under mid-span concentrated load. These beams are created by cutting the webs of standard I-sections in a particular zigzag pattern and rejoining the two parts by placing
