Experimental Study on the Dynamic Buckling of a Cylindrical Shell due to Seismic Excitation : Plastic Buckling due to Bending Load

Abstract

The fundamental characteristics of plastic dynamic buckling of a thin cylindrical shell due to seismic excitation, 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, as well as the threshold for postbuckling, were discussed.
