This study develops impact collapse problem of thin-walled members as follows: 1) A visco-plastic constitutive equation was expressed for characteristics after collapse of local buckling. 2) Experiments of impact collapse were done under eccentric compression load for square tubes. 3) Using the experimental data, the constitutive equation was shown to be practically useful.
