Imperfection sensitivity in I-section struts experiencing local and strong-axis global buckling mode interaction


Abstract eng:
An extension of recent work on strong axis global–local buckling mode interaction in thinwalled I-section struts is presented. The variational model is extended to include initial geometric, stressrelieved, local imperfections. An imperfection sensitivity study of the strut reveals a decreased load carrying capacity with increasing magnitudes of local imperfections and a particular sensitivity to localized imperfection shapes. An identical strut is constructed and analysed using the commercial finite element software Abaqus, showing excellent comparisons especially in the initial stages of the post-buckling path.
