Static and dynamic experimental study of strengthened inforced short concrete corbel by using carbon fabrics, crack path in shear zone

Fracture and Structural Integrity, 2015
The paper presents an experimental analysis of tracking the path of the cracks and crack growth in strengthened or repair reinforced concrete short corbels bonded by carbon fiber fabrics under static and dynamic loads.

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.

Combining GPR, Passive Seismic, and Load Testing With Computational Models in the Assessment of Historical Bridges: The Case Study of the Comboa Bridge

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The preservation of historical bridges usually requires extensive structural evaluations for possible damage detection. Therefore, effective techniques are essential for diagnosis and, consequently, proper maintenance and rehabilitation actions. The combination of techniques provides complementary data that support decision making.

Distributions of non‐native and native plants are not determined by the same environmental factors

Ecological Solutions and Evidence, Volume 5, Issue 4, October–December 2024.
Distributions of non‐native plant species are driven more strongly by anthropogenic variables than distributions of native plant species, though climate is the most powerful predictor in both species groups. Species distribution models should therefore be fitted with different variables based on the study species' degree of nativeness.

Effect of CFRP Sheets Strengthening Method on Behaviour of Modified Lightweight Foamed Concrete Beams

Journal of Engineering, Volume 2024, Issue 1, 2024.
This study has been adopted to examine the effect of carbon fibre‐reinforced polymer (CFRP) sheet strengthening methods on the flexural behaviour of modified foamed concrete beams reinforced with different steel reinforcement ratios, and it deals with the enhancement in flexural behaviour of conventional nonstrengthened FC beams. Twelve modified foamed

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.

Reinforced Concrete Corbels – State of the Art.

Journal of Materials and Engineering Structures, 2016
This paper represents a historical review, state-of-the-art review, on the experimental researches carried out on corbels in general and strengthening of corbels in particular. The corbels discussed are made of normal, high-strength and self-compacting concrete and subjected to two types of loading, monotonic and repeated loadings.

Experimental and Numerical Analysis of Omnidirectional Steel Moment Connection With Through‐Plate Panel Zone Under Cyclic Loading

Shock and Vibration, Volume 2024, Issue 1, 2024.
This paper proposes a new beam to column connection, namely, the omnidirectional steel moment connection with through‐plate panel zone, which enables the connection of more than four beams to a column in moment frames at any arbitrary angle. The proposed connection was experimentally and numerically analyzed under cyclic loading.

A Calculation Method for the Shear Strength of Steel Fiber-Reinforced High-Strength Concrete Corbels Based on the Softened Strut-and-Tie Model

Buildings
To investigate the shear performance of steel fiber-reinforced high-strength concrete (SFRHSC) corbels subjected to concentrated loading, an experimental program was executed on six specimens featuring welded anchorage for the upper longitudinal ...
