LATERAL-TORSIONAL BUCKLING OF CASTELLATED BEAMS

Abstract

An experimental study of the lateral stability of castellated steel beams is described. Two series of tests were conducted: a preliminary series on specially manufactured small-scale specimens designed to provide qualitative data, and a second series of eight full-scale tests using commercially-produced beams. The results of the preliminary series, subsequently confirmed by the full-scale tests, indicate that the presence of the castellations has negligible effect on lateral buckling behaviour.
