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 ...

EBI-strengthening of CFRP

Journal of Advanced Science, 2006
Carbon fiber reinforced (CFRPs) are increasingly commonly used composite materials based on carbon faiber. To evaluate the strength was used the tensile test, bending test and Carpy impact Test. We concluded that EB irradiation reinforced mechanical properties for CFPRP.

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin

Structural Concrete, EarlyView.
Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.

Numerical and experimental investigation of hollow steel columns strengthened with carbon fiber reinforced polymer [PDF]

Journal of Structural and Construction Engineering, 2016
In this research the hollow steel columns that strengthened with CFRP under axial compression has been investigated.Retrofit methods such as the use of steel plates increases the structural weight and in some cases using such method is difficult and ...

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 ...

Multiaxial Fatigue Behavior of AA6016 and AA6016 to DX54D SPR Joints: Fracture Mechanisms and Data‐Driven Rupp's Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The fatigue and fracture behavior of self‐piercing rivet (SPR) joints between AA6016 aluminum sheets (1–2 mm) and DX54D steel (0.95 mm) was studied under 90°, 45°, and 0° multiaxial loading. Pure shear (90°) loading produced the highest fatigue strength, whereas multiaxial (45°) loading resulted in reduced performance, with pure tension (0 ...
