Calculations of reinforced column bases according to the component method

<ns3:p>This paper presents an algorithm for evaluating the resistance and stiffness of a column base, based on the component method. The first part of the paper characterizes the adopted solution for the column-to-foundation connection, whose main element is a double-cantilever I-beam. The bottom flange of this beam is anchored into the concrete foundation using anchor bolts, while the shaft of the column is attached to the top surface of the upper flange of the beam. Based on the guidelines of the EN 1993-1-8 standard, literature studies, and the author's own analyses, fundamental equations were established for calculating the mechanical properties – resistance and stiffness of individual components of the column base. Subsequently, mechanical models of the analyzed solution were formulated, serving as the basis for determining the relationships for the base’s overall resistance MRd and stiffness S. The final part of the paper includes a numerical example demonstrating the application of the proposed procedure in the calculations of the reinforced column base.</ns3:p>
