Corner fastener calculation
Corner fastener calculation
(OP)
I'm looking formward to a hand calculation formula to calculate fastener load transfer at corner area. In this aera there is Nx, Ny and Nxy flow.

What i think i understand is that you have a fastener which as a biaxial load and a shear flow in the area. If this is correct, then i would simply take the root of the sum of the axial loads squared. Cant see what your talking about by trying to add in the shear flow, as it is a function of the axial loads applied to the structure?

I would like to calculation safety margin at one fastener which is localized at the corner of my panel. The flow which have to be transfered and which is taken from the dedicated FEM is Nx, Ny and Nxy (shear flow).
note: for current area (out of corners) the load transfered by the row of fastener is F = ((Nx^2+nxy^2)^0.5 x pitch. Therefore, I'm still looking for the same kind of formula for corner area where the fastener has to transfer (Nx, Ny and Nxy flows).
Vonlueke: I do not understand how you could sum-up Nx et Nxy directly... don't you do a resultant calculation?
