Optimizing different damaged reinforced concrete corbel characteristics utilizing CFRP sheets

Fracture and Structural Integrity
Concrete corbels are short cantilever constructions that may lose their strength over time because of loads that happen over and over again. As an external bonding method for reinforcement, carbon fiber-reinforced polymer (CFRP) strips are utilized to ...

Experimental Investigation on Shear Behavior of Double Sided Reinforced Concrete Corbels Using BFRP Bars

Zanco Journal of Pure and Applied Sciences
A reinforced concrete corbel is a short cantilever structural member extending from columns or walls, resisting mostly vertical loads by shear action. The paper presents an experimental investigation on the shear behavior of reinforced concrete corbels ...

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 ...

Colourful Urban Birds: Bird Species Successful in Urban Environments Have More Elaborate Colours and Less Brown

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.

Robustness of Dry‐Assembled Precast Wall and Coupled Wall‐Frame High‐Rise Structures With Voided Prestressed Slabs

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 ...

Performance Analysis of Self‐Resetting Pier–Beam Node of Sheet–Pile Bridge Based on Vehicle–Bridge Coupling Vibration

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.

Finite Element Performance Assessment of RC Columns Strengthened With Hybrid NSM Steel and FRP Bars Subjected to Static and Repeated Loads

Modelling and Simulation in Engineering, Volume 2025, Issue 1, 2025.
A numerical finite element analysis has been investigated in this paper to examine the performance of strengthened reinforced concrete (RC) columns with near‐surface mounted (NSM) fiber‐reinforced polymer (FRP) and steel bars under static and repeated loads using the finite element software ABAQUS/Standard.

Tension stiffening effects in reinforced concrete members [PDF]

, 1985
This thesis is in two parts which are related by the common theme of tension stiffening. Part I develops the concept of a stress-strain envelope to model the behaviour of the concrete in tension below the neutral axis of a reinforced concrete beam.
