Buckling load prediction using the VCT approach for different loading ranges on SST-2 cylinder (second vibration mode).

Max. load used for VCT; % of experimental buckling load	Predicted buckling load using VCT kN	Deviation from experimental results %
90.6%	47.96	3.9
80.6%	42.77	14.3 (fail)
70.6%	36.38	27.1 (fail)
