Machine learning-driven web-post buckling resistance prediction for high-strength steel beams with elliptically-based web openings

open access: yesResults in Engineering
The use of periodical elliptically-based web (EBW) openings in high strength steel (HSS) beams has been increasingly popular in recent years mainly because of the high strength-to-weight ratio and the reduction in the floor height as a result of allowing

Web-post buckling prediction resistance of steel beams with elliptically-based web openings using Artificial Neural Networks (ANN) [PDF]

open access: yesThin-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]

open access: yesArchives 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.

Finite Element Investigation on Web-Post Buckling of Perforated Steel Beams with Various Web Opening Shapes subjected under different shear-moment interaction [PDF]

open access: yes, 2011
The current method of assessment is based on FE models which still lack computational efficiency and are restricted by a number of limitations. Therefore, this work aims at the feasibility of developing FE models which are applicable to deformation and ...

Slender metal web stability analysis: Impact of initial imperfection on the mode of buckling [PDF]

open access: yesMATEC 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 access: yesOpen 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
