Bending on preloaded bolt
Bending on preloaded bolt
(OP)
Hello,
What is the most accurate way to calculate the failing point of a preloaded bolt connecting between a fixed metal roof and a cantilevered beam. See image attached.
Thank you in advance.

RE: Bending on preloaded bolt
there would be a small moment in the bolt, but reasonly negligible IMHO.
you could take it all out as bolt bending, bolt loading is then a combination of tension and bending, i'd suggest Rt+Rm = 1/RF or you could go with Rt^2+Rm^2 = 1/RF^2 or variations on a theme.

Since we don't have roofs on airplanes, you might get a more practical answer by asking the civil guys over in the structural forum.
RE: Bending on preloaded bolt
The beam is more than a meter long and the force reaches about
1 Kgf.
Dont you think the moment needs to be addressed ?
When you say "Rt+Rm = 1/RF"
what does Rt,Rm,RF mean ?

mind you, it does look like a diving board ...
