Abstract :-Nonlinear finite element analysis on GFRP reinforced concrete columns were performed usingABAQUS/Standard finite element code. A damage plasticity model was used to simulate the behaviour of reinforced concrete. The perfect bonding between GFRP rebars and concrete was simulated using an embedded element algorithm. A static Riks formulation was implemented to trace the stable load-displacement history of GFRP reinforced concrete up to failure. The numerical model was compared with the behaviour of three GFRP reinforced columns and two steel-reinforced concrete columns under concentric loading. This paper will show how the model described above reliably reproduced the peak axial stress, axial deformation at the peak stress, the post-peak behaviour, and the failure mode observed in the tests.
