Hi, I intend to verify a component, including a bolt joint, according to EN 13445-3 Annex C. My concern is how to show that the bolt joint fulfill the requirements according to EN 13445-3 Annex C.
I am familiar with traditional bolt joint calculations for example according to VDI2230. The bolt joint has metal-metal contact and an oring.
For admissible stress levels (design stress fd and ftest) Annex C makes reference to Clause 6. For bolts Clause 6 point to Clause 11 and 12 and further also to Annex G. Annex G makes reference to EN 1591.
Question: Do I have to dig deep into Annex G and EN 1591 to actually show that requirements are fulfilled? Or would it be allowed in a more simplified way to use the results from VDI2230 or even from a finite element calculation and show that requirements(according to EN 13445-3 Annex C) are fulfilled? For example define preload method, calculate bolt stresses in assembled and loaded condition, calculate contact clamping force etc according to CDI2230/FEA and then finally evaluate towards allowable limits that fulfill EN 13445-3 Annex C?
