Cold-formed steel structural elements subjected to time-dependent loading

TL;DRAbstract

This report summarizes the results obtained from a comprehensive study of the behavior of thin-walled, cold-formed members subjected to impact or shock loading. The influence of local buckling and the concept of effective width in the elastic post-buckling range on the dynamic response of these members is described. Analytical and experimental results for thin compression elements, beams and columns are discussed. Comparisons between the analytical and experimental results are presented. Application of the results obtained from this research to practical situations involving impact or shock loading of cold-formed members is also discussed.
