Abstract

This paper presents a three-dimensional nonlinear finite element (FE) model for exterior reinforcedconcrete (RC) beam-column joints (BCJ) shear-strengthened with embedded carbon fibre reinforcedpolymer (CFRP) bars. The BCJ were subjected to a combination of reversed cyclic loading at thebeam end and column axial load. The concrete damage plasticity model was selected to representconcrete tensile and compressive failure under reversed cyclic loading. The von Mises yield criterionwith isotropic hardening was used to describe the post-yield response of the steel reinforcement. Anelastic-brittle model was chosen for the embedded CFRP bars. The FE predictions were validatedagainst experimental and analytical results. The FE model predicted the experimental stiffness, peakload and damage evolution with good accuracy. Comparison between experimental, numerical andanalytical results showed that the FE model gave a conservative estimate of the joint shear strength.
