A closer look at the recent DNV-RP-C203 -publication shows that fully compressed stress range with no residual stresses does not lead to fatigue:
If the thread of the bolt is rolled, there exists residual stresses and the DNV reduction factor is not zero. If the compression load is big...
The mentioned example of the connection is just an example. There are no bending or tension loads, only compression load so the load range is purely on the compressive side.
The main question is (everything else is irrelevant), do bolts experience fatigue under fully compressed varying load and...
Bolts are seldom under compressive load, but what if we had an situation, where a non-preloaded bolt was under varying compressive load (load ratio R>1, i.e the loading is fully compressive).
For example, the situation could be a column base connection without grout where the anchor bolts and...
Yes of course. And there is base plate naturally.. But isn't the fatigue life longer when the load range is completely on the compression side compared to alternating or pulsating tension load? And how much bolt's FAT class increases when the varying load is fully compressive?
