Abstract
Symmetrical buckling of steel tube-like shell structures fully filled with a softer material is considered. Such a compound cross-section, after assum ing complete condensation of the contained material, is subjected to unifor m axial compression by means of two rigid end plates. We further assume sim ple boundary conditions on both ends with zero radial displacements. The pr oposed solution allows establishment of the effect of hoop stresses on the load-carrying capacity of the filled tube. (C) 2000 Elsevier Science Ltd. A ll rights reserved.
