Using the universal finite element software Abaqus, the mechanical behavior of carbon fiber reinforced ploymer (CFRP) sheet confined rectangle concrete short columns with corners under axial compression is analyzed. Results of nonlinear finite element method (FEM) analysis are in good agreement with experimental results, indicating that the finite element model established in this paper can well simulate the behavior of CFRP sheet confined rectangle concrete short columns with corners under axial compression. By using the finite element model, the influence of CFRP sheet layer, corner radius, section aspect ratio and concrete strength on the strength of confined concretes is studied.
