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, the failure mechanism and the limit states of the webs of steel girders are affected by the cumulative damage process generated by the many times repeated character of loading, and how this phenomenon influences the design of such girders.
