Proceedings, pages 337-346http://hdl.handle.net/11652/681In this paper the analysis of the damping behaviour of thin-walled composite columns with open stiffened cross-sections subjected to in-plane pulse loading is described. The pulse loading of a rectangular shape is concerned. The discussed problem of the dynamic interactive buckling is solved by the analytical-numerical method (ANM) using the Koiter’s perturbations method. A critical value of the dynamic load factors is determined according to the Budiansky-Hutchinson’s criterion for different value of the viscous damping ratio. The detailed calculations confirm that small damping does not affect the dynamic response of the thin-walled composite columns under the impact in-plane loading.encienkościenne koolumnydynamiczne interaktywne wyboczeniemetoda analityczno-numerycznaobciążenie dynamiczneArtykuł
