Elastic distortional buckling analysis of clod-formed thin-walled steel column with hole

Yao Yong-hon

Abstract

Cold-formed thin-walled steel columns are commonly provided with holes as bearing members to accommodate auxiliaty living facilities crossing in the low-rise lightweight steel residence structure.Study on the distortional buckling stability of cold-formed thin-walled steel members have widely been implemented in recent years by some researchers.The elastic distortional buckling stress calculation method for open-hole column is the key issues in stability problem of cold-formed thin-walled steel structural member.The design method of elastic distortional buckling combined with finite strip method and finite element method was proposed,which contained finite strip method based on modifying whole cross-section thickness and calculation formula in this study.It is shown that the proposed methods can be used for design specification.
