METHODOLOGY FOR THE COMPUTATION OF CRITICAL BUCKLING FORCE AT STEEL TUBES WITH FLATTENED ENDS

This contribution deals with a methodology for the computation of critical buckling force at steel tubes of a defined shape. Due to the simple joining on the gusset joint plates, a tube with flattened ends was chosen as a column shape. This contribution brings some information about a performed experiment, where the value of critical buckling force was being found out. Subsequently, it was computed by Rayleigh energy method and by differential equation. While computing the values, some differences were found out in the results which related to the used boundary conditions. The contribution brings some information about these differences and proposes a suitable way for the computation thus defined columns.
