Hey

I'm making a program for checking bolted endplates subjected to axial forces, shear forces, torsion and bending moments according to Eurocode 3. However I'm a bit stuck on finding the bearing resistance.
I've added a picture to make it easier to follow my explanation. Seeing as its's expected this endplate will experience shear force in x and y simultaneously, I would expect the resultant shear force to be what to check for. But in the eurocode edge distances e1 and e2 and bolt spacings p1 and p2 in bearing resistance check calculation are defined as whether they are parallell or perpendicular to the applied load, which I think is hard to define when using the resultant shear force.

My question is this; what's standard practice here?
Do I check bearing resistance in x and y direction and check against corresponding shear forces (this to me seems weird as we expect Fx and Fy to act at the same time)?
Or do I use the direction with the lowest bearing resistance against the resultant shear force (this seems very conservative, but safe)?
Or something else?

The total bearing resistance should be based on smallest of the individual resistances..

Thank you, let me just check if I understand correctly.
The procedure is first to calculate the bearing resistance both for x and y directions take the minimum of these two. And then lastly to check the resultant shear force against it.

Please correct me if I'm wrong.

The bearing resistance should be verified for bolt load components paralel to the edge and normal to the edge separately ..

Pls look to the following doc.
