Abstract

The buckling of geometrically imperfect columns under axial compressive pulse is studied. The transverse shear and rotary inertia terms are included in the analysis and their effects are investigated for various pulse frequencies. Dynamic buckling criteria for the different loading types are defined and buckling results are compared between displacement-controlled versus force-controlled loads and simply-supported versus clamped boundary conditions. The results show that the application of the classical beam theory overestimates the resistance of columns to dynamic pulse buckling.
