Curved beam analysis
Curved beam analysis
(OP)
A project I am working on requires a horizontally curved lintel beam with a radius = 9'-7". It will support a metal stud & gypsum bd. decorative wall that is 3'-0" wide & 4'-0" tall. In plan view the lintel will form a quarter circle. Where can I find analysis/design procedure for this lintel beam? To design this as a straight beam with a 2'-0" eccentric load seems overly conservative but appears to be the only way to apply AISC #9 guidelines.

Arc= 15'-0 5/8
Let arch length be your span for a simple beam with uniform load along the centerline.

The big issue is that after all is done and said and you've calculated the stresses to 8 decimal places, there's not any design code to give an allowable stress- you're on your own there. It will simplify matters if you use a square tube so you don't have lateral buckling issues.
