This paper presents a numerical study of the Shanley column under cyclic loading. The model includes intermediate deformation kinematics. The constitutive model is based on the Dafalias-Popov model. Results for fully reversed, symmetric load or displacement-controlled loading are presented. Under displacement-controlled loading, the model can exhibit a transient response which takes it away from its initial configuration, but the response eventually reaches a stable cycle. Under load-controlled loading, the model can either reach a limit cycle or develop a limit load instability that causes collapse. The responses that result in collapse are imperfection sensitive. In addition, the response of the model is also sensitive to the amplitude of the applied loading cycles.
