Distributed AutoML framework for multi‐objective optimization of concrete crack segmentation models

Structural Concrete, Volume 27, Issue 1, Page 998-1019, February 2026.
Abstract Monitoring cracks in concrete surfaces is essential for structural safety. While machine vision techniques have received significant interest in this domain, selecting optimal models and tuning hyperparameters remain challenging. This paper proposes a Distributed Automated Machine Learning (AutoML) framework for efficiently designing and ...

Life-cycle low-carbon design and assessment of UHPC beams integrating flexural capacity requirements

Low-Carbon Materials and Green Construction
The excellent mechanical properties of ultra-high performance concrete (UHPC) will reduce the cross-sectional size of UHPC beams, resulting in a decrease in the amount of UHPC and the carbon emission.

Recent Advances in Carbon Materials for Cathodes and Interlayers in Lithium–Sulfur Batteries

Small Structures, Volume 7, Issue 1, January 2026.
This review examines dimensional carbon materials (0D–3D) as hosts and interlayers for Li–S batteries. It details how structural morphology, heteroatom doping, and catalytic functionalization effectively mitigate the polysulfide shuttle effect, manage volume expansion, and accelerate redox kinetics.

MultiBlock‐SwinUNet: A Noise‐Robust Framework for Crack Segmentation of Multi‐Class Concrete in CT Images

IET Image Processing, Volume 20, Issue 1, January/December 2026.
Existing methods often struggle to balance accuracy and robustness against complex interference such as noise and artefacts inherent in industrial CT imaging. To overcome these limitations, we propose an innovative framework named MultiBlock‐SwinUnet. This architecture is designed to enhance feature extraction for different categories of concrete and ...

Experimental and theoretical study on seismic behavior of precast exterior UHPC-HSC beam-column connections

Case Studies in Construction Materials
This research evaluates the seismic behavior of precast ultra-high performance concrete (UHPC) and high-strength concrete (HSC) beam-column connections. Quasi-static test was performed on three UHPC-HSC connections and one cast-in-place connection.

Acoustic Emission‐Based Evaluation and Mechanistic Analysis of Instability Failure in Concrete Materials

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study presents a quantitative method for assessing concrete damage based on acoustic emission (AE) signal analysis. Employing AE to monitor damage evolution under uniaxial compressive loading in real time. The collected signals were subjected to two‐layer wavelet packet decomposition (WPD) to obtain four frequency bands.

Innovative Machine Learning Techniques for Sustainable Compressive Strength Estimation of Ultrahigh‐Performance Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
In this work, the compressive strength of high‐performance concrete (HPC) mixtures was estimated by four various machine learning methods based on Gaussian process regression (GPR). For this purpose, kernel functions including exponential, Matern, rational quadratic, and squared exponential were employed in modeling.
