Out-of-plane bending stress on an I-beam

[gmreit]

TL;DR

out of plane bending stress

I know the out of plane bending stress equation for a curved I beam but I am trying to figure out where it came from. sigmaR = tFlange * sigmaNormal/(radius of curvature)

You need to define what you are thinking about as "out of plane." This is out of what plane?

I think I may have figured it out. Let me finish what I have on paper
