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.
