The promising trend of thin-walled construction can be materialised just thanks to the beneficial effect of post-buckled behaviour. However, as a great part of steel structures are subjected to many times repeated loads (bridges, crane-supporting girders and the like), it is demonstrated, by means of the results of numerous experiments carried out by the authors in Prague, how the post-critical reserve of strength is affected by the cumulative damage process generated by the many times repeated character of loading, and how this phenomenon influences the design of structures.
