Abstract
Although performance of steel structures has been fairy well due to ductile material properties, during the Hyogoken-nanbu Earthquake (M=7.2), occurred at 5:46, 17th January 1995, various types of damages were found among steel structures and the elastic-plastic dynamic buckling induced through the seismic excitations is recognized as one of the most important problems in seismic design. The purpose of this paper is to describe a method of elastic-plastic large displacement analysis for buckling analysis of shells of revolution, and to discuss about the dynamic buckling characteristics of a steel circular pier comparing the computational results with the observed phenomena in Kobe City.
