AN ANALYSIS OF THE EFFECT OF HOLES PATTERNS ON COUPLED INSTABILITY OF PERFORATED THIN-WALLED MEMBERS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2014, Vol 59, Issue 1
Abstract
The buckling behaviour of vertical steel pallet rack columns is greatly influenced by the distribution of perforations punched continuously along their length. To study the influence of the holes patterns on the elastic coupled instabilities of thinwalled members, this paper uses an original modal identification method (based on the Generalised Beam Theory) which is able to provide the pure buckling modes participation (of global, distortional, local nature) in a general eigenvalue buckling mode given by the shell Finite Element Analysis.
