Background/Objectives: In this research, behavior of column base with box-shaped column under static loads has been examined via finite element method. Methods/Statistical Analysis: Column connection to column base and column base connection to foundation have been modeled with details, and the behavior of connection in form of moment-curvature diagram has been displayed by changing the parameters including column base plate thickness, diameter of anchor rod, axial load, distance between anchor rods, eccentricity of the column in the direction y, x, connection behavior in form of moment-curvature diagram. Results: The results indicate that the more column base plate thickness increases, in addition to increasing ultimate resisting moment, joint stiffness in the elastic curve will increase. Further, by decreasing diameter of anchor rod, rigidity of connection will increases and the connection behavior will get close to the state of changing the rigid forms. By decreasing the distance between anchor rods, joint stiffness and ultimate moment resistance will increase and formation will decrease.
