Název v původním jazyce

The Stress State in the Crack-Prone Areas of ?Breathing? Thin Walled Girders ? a Sensitivity Analysis

Popis výsledku v původním jazyce

The fatigue performance of thin-walled steel girders subjected to many times repeated loading is characterized by the development of fatigue cracks which initiate as a result of the coupled effect of repeated plate buckling and cumulative damage in the girder, at the toes of the fillet welds connecting the flanges and stiffeners with the web sheet. The results of numerous tests conducted with the view to thoroughly study the phenomenon exhibit a large scatter. This is due to various factors, but mainlyto the great and by and large unpredictable effect of initial imperfections on the state of stress in those zones of the girder where fatigue cracks initiate and propagate. That is why the objective of the contribution is to report about the main conclusions of a sensitivity analysis performed by the authors from Brno, via the geometrically and materially nonlinear large deflection theory, with the view to ?map? the aforesaid effect.
