Reinforcement response prediction of composite‐concrete beams with crack patterns and deep learning

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6638-6655, 29 December 2025.
Abstract Using fiber‐reinforced polymer reinforcement in concrete (FRP‐concrete) to form composite‐concrete structures is increasingly important in civil and infrastructure applications because of its high strength, durability, and corrosion resistance. However, one of the main challenges of the FRP‐concrete structure is the brittle failure mode, which

Steel–Mortar and Flexural Mortar–Mortar Bond Strengths of Metakaolin‐Based Geopolymer

Engineering Reports, Volume 7, Issue 11, November 2025.
Metakaolin‐based geopolymer mortar demonstrated significantly higher interfacial bond strength than cement mortar across both mortar–mortar and steel–mortar testing, with performance influenced by interface transition zone (ITZ) roughness and curing age.

Short‐length mechanical bond anchorage for reinforcement bars made of FRP: Experimental and numerical investigations

Structural Concrete, Volume 26, Issue 1, Page 821-836, February 2025.
Abstract The availability of fiber‐reinforced polymers (FRP) as an alternative for conventional steel reinforcement in concrete construction is increasing. To widen the scope of application, for example, in the case of prestressing, and to improve the bond behavior at the bar ends, end anchorages need to be considered.

Poststrengthening Remote Monitoring in Practice: A Case Study of RC Structure Renovation

Journal of Engineering, Volume 2025, Issue 1, 2025.
Reinforced concrete (RC) structures are widespread globally, requiring systematic monitoring and proactive maintenance due to ageing, evolving demands and environmental exposure. Prolonging the service life of existing RC structures to meet modern requirements promotes sustainability by reducing waste, conserving resources and minimising environmental ...
