This study is dedicated to the development of a generalized confinement model applicable circular concrete columns confined by FRP full and partial arrangements. To simulate axial stress versus strain curve, new strength proposed addressing relation pressure during loading , whose calibration was based on an extensive set test results. By combining theoretical basis experimental observations, i...

The accurate prediction of reference points on the axial stress–axial strain relationship fiber-reinforced polymer (FRP)-confined concrete is vital to pre-design structures made with this system. This study uses an artificial neural network (ANN) for predicting hoop rupture (εh,rup) and transition zone, namely (εc1) stress (f’c1), stress–strain curves FRP-confined concrete. These are key parame...

Despite the many axial confinement models already proposed for determination of peak compressive strength fiber-reinforced polymer (FRP) confined concrete columns, they are, in general, applicable only to columns circular or square cross-section, with full partial arrangements. In this study, by proposing a cross-sectional and confining system unification approach, new model is developed calibr...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...
