Detection of delamination in RC structures using wavelet packet analysis

open access: yes, 2010
This paper presents a novel technique to detect the delamination between steel bars and concrete in RC structures using wavelet packet analysis. A damage index is constructed based on the wavelet packet component energy change.

Analysis of steel plate shear walls

open access: yes, 2010
In the past three decades the steel plate shear wall (SPSW), also known as the steel plate wall (SPW) has been used in various buildings throughout Japan and North America. In this paper, existing literature on steel plate shear walls is briefly reviewed.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Behaviour of novel blind-bolted joints with different strengthening components

open access: yes, 2015
Steel-concrete composite structures with concrete-filled steel tubular (CFST) columns have been widely used for multi-storey and high-rise buildings owing to their high structural efficiency and significant economy. Because of the difficulty of accessing

Nonlinear Finite Element Analysis of Tubular Steel Wind Turbine Towers near Man Door and Ventilation Openings to Optimize Design against Buckling

open access: yesVibration
The safe and cost-effective design of wind turbine towers is a critical and challenging aspect of the future development of the wind energy sector. This process should consider the continuous growth of towers in height and blades in length.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Feature of fire resistance calculation of steel structures with intumescent coating

open access: yes, 2018
The problem of estimation of fire resistance of steel frame structures with intumescent coatings is considered. It implies that both physical properties of a covering (its thickness and structure) and mechanical properties of a metal structure change ...

Behaviour and design of webs in high strength steel under flexural loading

open access: yes, 2005
The flexural behaviour of steel beam sections subjected to flexural loading has been studied extensively, and detailed design methods developed. These design methods have been developed on a broad database of experimental work carried out on so-called ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Behaviour of composite beams under negative bending and axial tension

open access: yes, 2011
Composite steel-concrete beams are used in many types of structures, including steel framed buildings, bridges, stadiums and car parks. Composite beams are being increasingly used in situations where combinations of bending, shear and axial force may be ...
