The procedure of calculation of steel column bases with stiffeners including plastic distribution of stresses in concrete has been shown. The strain model from section analysis, similar to model used in calculations of reinforced concrete columns has been used in this purpose. The assumption of linear strain of base plate under stiffeners and column has been made, according to Bernoulli-Euler Theory. The displacements of compressed part of columns bases have been associated with deformations of concrete foundation. Limitations of dimensions of compression zone have been defined based on results of FEM analysis. Ultimate compressive strain in the concrete under compression and bending, according to Eurocode 2 has been taken into consideration in the procedure. Deformation of base plate based on stiffness coefficients used in determining of rotational stiffness of steel joints has been assumed in the tensioned part. Incomplete utilisation of bolts resistance due to insufficient deformation has been also included. All the mentioned assumptions results in universal procedure that allows calculation of resistance of column bases under any combination of axial force and bending moment. Finally design example with an entire proceeding has been presented.

This paper presents partial results of a research program under way at Laval University for which the main goal is to introduce the behaviour of steel connections into commercial structural analysis software. The objective of this paper is to derive analytical characterization equations for three commonly used steel column base connections. The procedure to derive these equations is based on a curve standardization theory that requires a number of experimental results in the form of moment–rotation curves that characterize the behaviour of column base connections. Because of a lack of available experimental results, data were obtained from finite element models. The design of a simple steel structure introducing the semi-rigid behaviour of column bases is presented as an example. It shows that consideration of the semi-rigidity of column base connections increases the accuracy of the analysis results and leads to a decrease in structure weight and deformation.Key words: analysis, base, behaviour, column, connection, frame, partial, rigidity, steel, structure.
