The con-siderations are based on the classical linear theory of thin-walled beams with non-deformablecross-section introduced by Vlasov [1]. Both lateral braces and braces that restraint warping andtorsion of the cross-section have been taken into account. In the numerical examples dealing withI-column, the functions describing the influence of location of the braces with unit stiffness on thecritical load of torsional and flexural buckling are derived. The linear approximation of the exactrelation of the critical load due to the variation of the stiffness and location of braces is determined.}, type={Artykuły / Articles}, title={Analiza wrażliwości siły krytycznej słupa cienkościennego ze stężeniami}, title={Sensitivity Analysis of Buckling Loads of Bisymmetric I-Section Columns with Bracing Elements}, URL={http://www.journals.pan.pl/Content/83709/mainfile.pdf}, keywords={sensitivity analysis, thin-walled beam, stiffener, critical load}, }
