State-of-Art on Workability and Strength of Ultra-High-Performance Fiber-Reinforced Concrete: Influence of Fiber Geometry, Material Type, and Hybridization
Qi Feng, Weijie Hu, Lu Liu, Junhui Luo
Structural Durability & Health Monitoring, Vol.19, No.6, pp. 1589-1605, 2025, DOI:10.32604/sdhm.2025.072955
（This article belongs to the Special Issue: Innovative and Sustainable Materials for Reinforced Concrete Structures)
Abstract Ultra-high performance fiber-reinforced concrete (UHPFRC) has received extensive attention from scholars and engineers due to its excellent mechanical properties and durability. However, there is a mutually restrictive relationship between the workability and mechanical properties of UHPFRC. Specifically, the addition of fibers will affect the workability of fresh UHPFRC, and the workability of fresh UHPFRC will also affect the dispersion and arrangement of fibers, thus significantly influencing the mechanical properties of hardened UHPFRC. This paper first analyzes the research status of UHPFRC and the relationship between its workability and mechanical properties. Subsequently, it outlines the test… More >

Flexural Performance of UHPC-Reinforced Concrete T-Beams: Experimental and Numerical Investigations
Guangqing Xiao, Xilong Chen, Lihai Xu, Feilong Kuang, Shaohua He
Structural Durability & Health Monitoring, Vol.19, No.5, pp. 1167-1181, 2025, DOI:10.32604/sdhm.2025.064450
（This article belongs to the Special Issue: Innovative and Sustainable Materials for Reinforced Concrete Structures)
Abstract This study investigates the flexural performance of ultra-high performance concrete (UHPC) in reinforced concrete T-beams, focusing on the effects of interfacial treatments. Three concrete T-beam specimens were fabricated and tested: a control beam (RC-T), a UHPC-reinforced beam with a chiseled interface (UN-C-50F), and a UHPC-reinforced beam featuring both a chiseled interface and anchored steel rebars (UN-CS-50F). The test results indicated that both chiseling and the incorporation of anchored rebars effectively created a synergistic combination between the concrete T-beam and the UHPC reinforcement layer, with the UN-CS-50F exhibiting the highest flexural resistance. The cracking load and… More >

Investigation on Shear Performance of Concrete T-Beam Bridge Strengthened Using UHPC
Zhiyong Wan, Guozhang Luo, Pailin Fang, Menghui Ji, Zhizhao Ou, Shaohua He
Structural Durability & Health Monitoring, Vol.19, No.5, pp. 1327-1341, 2025, DOI:10.32604/sdhm.2025.065177
（This article belongs to the Special Issue: Innovative and Sustainable Materials for Reinforced Concrete Structures)
Abstract This investigation examines the shear performance of concrete T-beams reinforced with thin layers of ultra-high performance concrete (UHPC) through an approach that integrates experimental evaluation, numerical simulation, and practical project verification. The research is based on a real bridge, and in accordance with the similarity principle, three reduced-scale T-beams with varying UHPC thicknesses were fabricated and tested to examine their failure modes and shear behaviors. A finite element model was created to enhance understanding of how UHPC reinforces these structures, while also considering the effects of material strength and arrangement. In addition to the laboratory… More >

Sensitive Analysis on the Compressive and Flexural Strength of Carbon Nanotube-Reinforced Cement Composites Using Machine Learning
Ahed Habib, Mohamed Maalej, Samir Dirar, M. Talha Junaid, Salah Altoubat
Structural Durability & Health Monitoring, Vol.19, No.4, pp. 789-817, 2025, DOI:10.32604/sdhm.2025.064882
（This article belongs to the Special Issue: Innovative and Sustainable Materials for Reinforced Concrete Structures)
Abstract Carbon nanotube-reinforced cement composites have gained significant attention due to their enhanced mechanical properties, particularly in compressive and flexural strength. Despite extensive research, the influence of various parameters on these properties remains inadequately understood, primarily due to the complex interactions within the composites. This study addresses this gap by employing machine learning techniques to conduct a sensitivity analysis on the compressive and flexural strength of carbon nanotube-reinforced cement composites. It systematically evaluates nine data-preprocessing techniques and benchmarks eleven machine-learning algorithms to reveal trade-offs between predictive accuracy and computational complexity, which has not previously been explored… More >
