Abstract
Fiber Reinforced Polymer (FRP) jacketing is frequently used to enhance the performance of concrete columns. The strength and ductility of a concrete column increase after FRP jacketing mainly because of concrete’s improved behaviour under confinement. To achieve a reliable retrofit design, engineers often need to understand how much the performance is improved after FRP jacketing. For that purpose, numerical modelling is often necessary. The success of finite element analysis depends on an accurate concrete constitutive model and therefore, to capture confinement changes within a finite element model, concrete multi-axial behaviour needs to be adopted. Phenomenological elastic-plastic-damage models are widely used for the numerical modelling of concrete because of their capability of representing 3D concrete behaviour considering permanent inelastic deformations as well as degradation of material moduli beyond the elastic range. This paper aims to implement an elastic-plastic-damage model to simulate FRP-jacketed concrete columns. The material model is validated against existing experimental data and comparisons with the results of models developed in ABAQUS software. It is shown that the proposed modelling approach is capable of providing an accurate behaviour of square concrete columns confined with reinforcements and FRP jackets under compression. After the validation of the model, a parametric study was conducted to illustrate the effect of partial wrapping on the behaviour of retrofitted columns.
