Abstract
This paper presents nonlinear finite element analysis of eccentrically loaded circular Reinforced Concrete (RC) column confined with Carbon Fiber Reinforced Polymer (CFRP). The purpose of this study is to validate the proposed plasticity-fracture model of Piscesa et. al. (2019) to model RC column confined with CFRP under eccentric loading. The software used in the simulation is and inhouse finite element package called 3D-NFLEA. Two available specimens in the literature are investigated and an existing numerical result is also included for comparison purposes. From the analysis and investigation, it was found out that the negative effect of confinement at the outer concrete region was caused by significant difference between the concrete dilation rate at the inner to the outer concrete core region. In addition, From the comparison, close agreement between the numerical models and the available test result are discovered in this study. As for the column ductility, it was found out that the column ductility was higher for column with larger initial load eccentricity.
