| Summary: | The article presents an algorithm for assessing the resistance and stiffness of a reinforced column base, which is based on the component method. The main part of the study formulates a mechanical model of the reinforced column bases, in the form of a stiffened base plate fixed to the concrete by eight anchor bolts. The adopted structural solution was analyzed using the component method for calculations. By referring to standard guidelines and existing literature, the mechanical properties, such as resistance and stiffness, of individual components of the column base are determined. Equivalent mechanical models were then formulated using equilibrium conditions and deflection compatibility, enabling the derivation of formulas for the bending resistance Mj .Rd and the initial stiffness Sj .ini of the entire column base. In the final part of the work, a comprehensive numerical example is provided to demonstrate the application of the presented method in calculations of the reinforced column bases. |
