Analysis of the Methods of the Connection Calculation

In the present research work the compression analysis of the method of calculating joint connections made of roll-welded profiles, specified in the “Guide on structural steel design (for Construction Standards and Regulations II-23-81*)” (hereafter - SNiP), was performed. According to item 15.16. of the guide [1], two types of joints, F and F_r, were chosen as the study object. During the research several combinations of the construction of such joint types were accepted and modelled with the help of the software solution IDEA StatiCa which does calculations based on the component-based finite element method (hereafter - CBFEM). The obtained results from the software solution were checked against the results calculated by the procedure described in the guide. It was established that during the compression calculation of the connections, the load-carrying capacity of the joint is reduced by the receiving gusset, which is disregarded in SNiP. The research was conducted with the help of the CBFEM used by the software solution IDEA StatiCa.
