The machinery products and the construction structures often include some structure components which should be treated as long pillars. In the design of those structures, the buckling load due to a collision or an earthquake is usually evaluated by taking the safety factor large enough to that for the Euler buckling. In the recent trend of the light-weight design or the cost-reduction for raw materials, the exact evaluation of the dynamic behavior of long pillar component is now being performed. In this study, the effects of the shape and dimensions of the column under dynamic loading and the duration of the applied load on the buckling behavior of the column are systematically investigated mainly by the numerical simulation with use of the FEM code MSC.
