Behavior of Reinforced Concrete Corbels Strengthened with CFRP Strips Subjected to Monotonic and Repeated Loading

Tikrit Journal of Engineering Sciences
Concrete corbels are short cantilevers subjected to monotonic and repeated loads. Repeated loads generally negatively affect the concrete structural members' strength as they decrease the resistance to external loads.

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.

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 ...

Numerical simulation of double-sided concrete corbels internally-reinforced with GFRP bars

Composites Part C: Open Access, 2020
Three-dimensional (3D) finite element (FE) models were developed in this study to simulate the nonlinear structural behavior of double-sided concrete corbels internally-reinforced with glass-fiber reinforced polymer (GFRP) bars.

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
