italian legislation tree fatigue static

[christoph]

Hello everyone, my name is christoph, I studied abroad-austria and I want to carry out state examination in mechanical engineering.
I would have a question about the regulations that are typically used for mechanics.
what is the current norm that is used for testing fatigue and static for trees? (in austria we used din743).
I have seen that the criterion of gough-pollard is used in the folgies of various universities ect, but I did not find a definitive norm with which I can prepare and that imagino is given during the state examination.

Thank you!

In reality, especially at university level, unfortunately the regulations are not used. Keep in mind that for constructions and bolts still persist with the one cnr10011 which was withdrawn about twenty years ago.
The religion 743 you can use it at work or by kisssoft.
in Italy there are books of science of buildings and on these free there are explained ancient methods, theories at the base.
then once you have made the static calculation of the tree and you have to do a fatigue analysis you have to follow this scheme:then you can calculate the main stress parameters:
and then if you have to use whöeler go to This is post.

the same formulas are used in technical institutes, the regulations are only quoted for completeness of information but the formulas are always canonical, I think for at least 50/60 years.

Have a good night.
