The fundamental characteristics of plastic dynamic buckling of a thin cylindrical shell due to seismic exicitation, where bending load was predominant, were clarified experimentally. The relationship between seismic response displacement, acceleration, strain of cylindrical shell model and input acceleration was investigated. The dynamic buckling load was compared with that for static buckling, and the differences between them were discussed as well as the threshold for postbuckling.
