Column-base connections are one of the most important elements in steel structures which connect the steel frame to the foundation. Therefore, in structures erected in seismic areas, these connections are critical to convey cyclic inertia forces to the frame. In this paper the author performed a parametric study utilizing Finite Elements Method (FEM) to investigate the cyclic behaviour of the connection. Primarily, the modeling method is verified and calibrated by the use of available experimental data. Afterwards, the parametric computer models are made. Effect of the parameter of column dimensions on overall behavior of connection is investigated for the first time. The mentioned parameter plays an important role in simple column-base connection’s behaviour as it alters the moment distribution in the base plate. Additionally, two other separate parameters are considered and their individual impact on the total behavior of joint is investigated.
