Behavior of structural concrete frames with hybrid reinforcement under cyclic loading

Fracture and Structural Integrity, 2021
A substantial amount of work was carried out on the use of fiber-reinforced polymer (FRP) in reinforced concrete structural elements, which demonstrated considerable inelasticity or deformity through monotonic and cyclic loads. Even so, the action of FRP

Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams

International Journal of Concrete Structures and Materials
AbstractThe current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges. Given the significant improvement in GFRP material properties, this study investigated the bond strength of sand ...

Dimensional stability and water transport behavior of concrete with high contents of wind‐turbine blade waste

Structural Concrete, EarlyView.
Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, EarlyView.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...
