Optimization of thin-wall cylindrical shells with compliant cellular-solid cores
… suggested that a compliant core increases the elastic buckling resistance of a cylindrical shell over that of a hollow cylinder of the same weight. In this thesis, we extend the linear-elastic buckling theory by coupling basic plasticity theory to provide a more comprehensive analysis of …

Experiments on Cold-Formed Steel Beams with Holes
Experimental testing and elastic buckling studies were performed on 68 C-section cold-formed steel joists with unstiffened rectangular web holes. Four Steel Stud Manufacturers Association (SSMA) cross-section types; 800S200-33, 800S200-43, 1000S162-54, and 1200S162-97, were evaluated to explore the …

Mechanical behaviour of steel hollow section columns subjected to damage – experimental study and finite element modelling
… levels of damage were examined using both linear elastic and non-linear buckling analysis approaches. The results indicated a substantial reduction in the failure strength of the HSS members due to damage. However, the elastic buckling loads of the hollow sections were not significantly affected. …

Lateral-torsional buckling behaviour of monosymmetric steel sections formed with flange upstands
The study of the lateral-torsional buckling behaviour of steel beams has been largely focused on doubly symmetric beams and less so on monosymmetric sections. Monosymmetric sections, however, do offer some advantages over doubly symmetric beams if the monosymmetry is applied in a way that it can be …
