FE modelling of bond interaction of FRP bars to concrete [PDF]

, 2006
In this paper a computational modelling approach is used to investigate the bond behaviour of fibre-reinforced plastic (FRP) bars in concrete. Two finite element packages (ANSYS and ABAQUS) are used to model the bond interaction of FRP reinforcing bars ...

Hygrothermal Aging and Decoupled Axial‐Radial Compressive Failure Mechanisms in Glass Fiber Reinforced Epoxy Filament‐Wound Composite Tubes

Polymer Composites, EarlyView.
Composite cylinder under axial and radial compression. ABSTRACT This study examines the hygrothermal degradation of filament‐wound glass fiber‐reinforced epoxy composite tubes designed for application as liners in oil and gas systems, focusing on their response under axial or radial compression.

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 ...

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 ...

Effect of entry sheet on hole position accuracy when drilling of printed circuit boards

Nihon Kikai Gakkai ronbunshu, 2017
Recently, the diameter of through hole on printed circuit board (PCB) has become smaller with downsizing of electric devices. However, the drilling small diameter through hole includes some problems such as hole position accuracy and hole bending.

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
