Quasi-static axial crushing of top-hat and double-hat thin-walled sections

摘要

Some recent theoretical predictions and experimental results are reported for thin-walled top-hat and double-hat sections subjected to static axial crushing forces. The phenomenon of progressive crushing is explored using a theoretical procedure which is based on the plastic methods of analysis for superfolding elements. The theoretical predictions are compared with some recent experimental results on thin-walled mild steel sections.
