Abstrakt
This paper deals with local dynamic buckling of thin-walled girder segments (short
beam-columns) subjected to bending. Various shapes of pulse loading (triangle, trapezoid
and rectangle) with a duration corresponding to the fundamental period of vibration
were taken into account. Assumed boundary conditions correspond to a simple support,
this agrees with conditions that exist in the place of the diaphragm in a long spar. The
problem was solved by finite element method. In order to determine the critical load
pulse amplitudes Volmir, Budiansky-Hutchinson, Ari-Gur and Simonetta criteria were
employed.
