STUDY OF CFRP GEOMETRY ON SHEAR STRENGTHING OF RC CORBELS
NTU Journal of Engineering and Technology, 2023 This study adapts the geometry of CFRP used as a strengthening material to improve the shear strength of reinforced concrete corbels. The experimental work investigated using CFRP with specific geometry that focused on the size and magnitude of CFRP ...

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Reinforced concrete (RC) deep beams are increasingly used in structural applications such as offshore platforms, high‐rise buildings, foundations, and nuclear facilities. However, the absence of a universally accepted strut‐and‐tie method (STM) for their design remains a critical challenge.

EFFECT OF USING SLURRY INFILTRATED FIBER CONCRETE ON THE BEHAVIOR OF REINFORCED CONCRETE CORBELS
Journal of Engineering and Sustainable Development, 2021 This paper experimentally presents the behavior and strength of slurry infiltrated fiber concrete (SIFCON) corbels. The program included 3 specimens in which steel fiber volume fractions were varied (6,8, and 10) %. All specimens had a constant shear span to depth ratio (a/d=0.7) and were of the same width, length, and thickness.

Innovation and modernization of Gabčíkovo lock chambers
Structural Concrete, Volume 26, Issue 4, Page 4015-4029, August 2025.Abstract From 2019 to 2023, extensive innovation and modernization took place at the lock chambers of the Gabčíkovo waterworks to increase the safety and intensity of the water transport. The waterworks is located on the Danube River about 60 km southeast of Bratislava—the capital of Slovakia.

Dynamic Test of Negative Stiffness Damped Outrigger With Damping Amplification
Earthquake Engineering &Structural Dynamics, Volume 54, Issue 4, Page 1141-1155, 10 April 2025.ABSTRACT This paper proposed a novel negative stiffness damped outrigger with damping amplification (NSDO‐DA) through a smart combination of an L‐shape lever, a precompressed disc spring brace (DSB), and a viscous damper. A theoretical model of the NSDO‐DA considering nonlinear adaptive negative stiffness, damping amplification of nonlinear viscous ...

Ecology Letters, Volume 28, Issue 4, April 2025.Urban bird communities are more colour‐diverse after accounting for species richness. We also found that bird species that do well in urban environments are less likely to be brown and exhibit more elaborate colours, but not higher sexual dichromatism. ABSTRACT Rapidly expanding urbanisation presents significant challenges to wildlife.

The Structural Design of Tall and Special Buildings, Volume 34, Issue 1, January 2025.ABSTRACT Precast concrete structures are recognized among the structural typologies that may mostly suffer from progressive collapse as a consequence of local unpredicted damage, also due to past accidents occurred in buildings employing old precast technologies neglecting the basic robustness criteria and characterized by poorly detailed and/or ...

Shear Strengthening of Corbels with Carbon Fibre Reinforced Polymers (CFRP)
Materiales de Construccion, 2010 Corbels constitute what are known as “disturbed” regions in concrete structures, where typical shear failure may be anticipated on the grounds of small shear span-to-depth ratios.

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.To address the issue of excessive stress at the secondary pier–beam joints of multispan continuous sheet–pile bridges caused by large longitudinal displacements, this study proposes a novel structural configuration incorporating prestressed self‐resetting reinforcement at the pier–beam connection.
