Finite element and theoretical investigations on PVC–CFRP confined concrete columns under axial compression

This article examines the performance of Carbon Fibre Reinforced Polymer (CFRP) on Concrete Filled with Vinyl Chloride Tube (CFPT) columns under axial compression. Firstly, 44 CFPT specimens from literature were analyzed using ABAQUS software to understand compressive behavior applied displacement. Secondly, 268 are simulated influence CFRP these control a varying number FRP layers and wrapping depth. Other variables such as unconfined concrete strength, thickness PVC tube, size slenderness ratio also studied. Studies extended confinement damage plasticity model analysis CFRP-CFPT (CCFPT) columns. Relationships between load-carrying capacity CCFPT properties developed. The effect parameters leads development analytical models. It is an advantage applying new type composite in various applications.
