Abstract

The purpose of this study is to examine the effects of initial imperfections on the large deformation behavior governed by local buckling of square hollow section members. After understanding the initial imperfections of real members, the effects of material and geometric imperfections on the large deformation behavior of the members are examined by axial compression analysis of simple loading condition. It is shown that the geometric imperfections of plate elements significantly affect and other initial imperfections owing to the manufacturing process do not much affect the local buckling behavior of the members.
