2 104 106 108 In older product information and data sheets, this basic suitability of DX fasteners for cyclic<br />
loading was emphasized by defining the recommended loads as cyclic recommended<br />
loads. At the time that this product information was assembled, a true safety concept for a<br />
strict check of DX fastenings subject to fatigue loading was not available. With Eurocode 3,<br />
this is today available. If a fatigue design analysis is carried out, it is important – as with static<br />
design – that adequate redundancy is provided.<br />
Failure of the sheet<br />
In cyclic load tests, failure of the steel<br />
sheet itself is common.
