VOD and MichSt,
Thanks for the replies. The structure in questions is actually a beam used in an aircraft component. It is part of a space frame that is bent to provide clearance and thus has a tight radius of curvature at what I refered to as the haunch.
VOD, when you suggest a lateral effect, what are you specifically refering to? My section is a C-channel and from my understanding of the problem, the beam will bend and where the curvature is tightening, then the flanges close in on eachother and the web bends outwards. Conversely the flanges bend away from eachother and the web bends towards the section centroid when the curvature increases. I need to stabilize the flanges to eliminate the transverse stress arising from the bending action. I was going to use gusset type stiffeners but need to know how to determine if the spacing I have is appropriate.
MichSt,
I've been using Blodgett, Section 5.11-7, subparagraph 4, for my analysis. Section 4.4 does not cover the transverse bending stress experienced in a curved beam.
Thanks for your replies.
