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

Results 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]

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 ...

EC3 design of web-post buckling resistance for perforated steel beams with elliptically-based web openings

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 resistance calculation of perforated high-strength steel beams with elliptically-based web openings for EC3

Structures, 2023
There has been an increase in the use of high-strength steel, as it provides lightweight structural members by satisfying environmental and economic issues. This paper aims to implement high-strength steels in the web-post buckling resistance equation, which was based on the truss model according to EUROCODE 3, presented previously by the authors.

Composite action on web-post buckling shear resistance of composite cellular beams with PCHCS and PCHCSCT

Engineering Structures, 2021
This paper aims to study the composite action on web-post buckling (WPB) resistance of composite cellular beams with precast hollow core slab (PCHCS) units and with precast hollow core slab units with concrete topping (PCHCSCT). Geometrical and material non-linear analyses are performed.

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.

Design of Cellular Members under Axial-Shear-Flexure Interaction [PDF]

Journal of Applied and Computational Mechanics
Due to lack of a design resistance for cellular beam-columns under the axial-shear-flexure interaction, the design interaction resistances were investigated through a validated finite element analysis.

Web-post buckling resistance prediction models of stainless-steel cellular beams using machine learning algorithms

Advances in Science and Technology Research Journal
Cellular steel beams are increasingly used in construction projects due to their decorative and economical characteristics, enabling long spans that reduce the number of columns and footings in the structure, thus shortening construction times and reducing infrastructure costs.

Magnetotransport Signatures of Spin–Orbit Coupling in High‐Temperature Cuprate Superconductors

Advanced Science, EarlyView.
Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,
