This paper studies the effect of various parameters of an analytical model for reinforced concrete flexural members under axial and bi-directional lateral loads, developed by Shing-Sham Lai. The model assumes all inelastic flexural rotation to concentrate in an inelastic component, placed at the critical section at the member end. The inelastic component consists of five uniaxial springs to represent the deformation and resistance of the reinforcing bars and concrete within the critical section. The method was demonstrated to be simple and reliable to simulate the behavior of reinforced concrete columns under triaxial loading. However, the method to define the properties of the springs has not been precisely defined. Therefore, various methods are examined to evaluate the critical parameters of the model in the simulation of the observed behavior of reinforced concrete columns under varying axial load and two-directional horizontal load reversals. The model, with parameters defined in this paper, is shown to simulate important aspects of the reinforced concrete column behavior.
