This paper presents the application of the component method to steel column bases. The decomposition of the connection into components is described. An analytical model is presented to determine the moment resistance and the rotational stiffness of column bases under axial forces. The analytical model is verified with test results. A sensitivity study of the base plate thickness and the anchor bolt length is presented.

Key words: Base plate, component method, analytical model, tests, design model
