I am having a bit of a problem with a shear flow problem. I have a WF with strong axis bending (and some torsion) that is getting a vertical plate welded to (1) side of it.
This plate is to take out the torsion. When I am calculating the shear flow, the A' is the Area of the plate, but y' is the distance from the centroid of the composite section to the centroid of the connected piece (plate). In this case the centroidal axes are coincident, and y' = 0. This is obviously problematic because I can not calc shear flow with this. I have considered calcing the shear flow at the juncture of the web/flange and distributing it based on relative thickness between the flange and plate; this is not at the EXACT juncture that I am seeking, but I feel it is close enough since the weld will most likely be overdesigned by a significant factor.
Does anyone have any suggestions.
