rolling of structural shapes in circular arch
rolling of structural shapes in circular arch
(OP)
when you roll a structural shape such as W12X40 in a radius of say 6' how does it effect its strength and E?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Given that, if the material is cold-worked, you will have some change in the yield but you really have no way to account for it with a hot-rolled shape. You will also have some distortion of the cross section which gets worse depending on the radius and the cross-sectional geometry.

With a W12x40 at a 6' radius, if you can't bend it, you can probably fab up an equivalent section out of plate/bar.

Also remember to consider carefully the ability of the section to laterally buckle.
