Breathing-induced fatigue in thin-walled construction. The way to check it
Original language description
Several years ago, the authors started an experimental investigation into the breathing phenomenon of the webs of thin-walled steel girders, which to date comprised more than two hundred tests. The cumulative damage behaviour generated by web breathing was analysed, the process of the initiation and propagation of fatigue cracks induced thereby was studied, and their impact on the failure mechanism and the fatigue limit state of the girders was determined. It was found out that the above phenomenon ledto a significant "erosion" of the beneficial post-buckled reserve of strength, so characteristic of the performance of thin-walled construction under the action of quasiconstant loading. Therefore, S-N curves were established for (i) the fatigue limit state (determining the maximum load range that the girder can sustain) and (ii) the onset-of-the-first-fatigue-crack limit state, which specifies those periods, given by the number of loading cycles, after which a check of the plate element
