Hey all,
I have a built-up shape consisting of (4) channels welded together that form a sort of box section, see attached. I am trying to determine the Torsional Warping Constant Cw and Saint-Venant Torsion Constant J for this combined section. These constants are required for finding the bending and compression capacities per AISI S100 code. I have the Cw and J values for each individual channel, but cannot find a way to calculate the combined values. I have searched for similar threads on here, but not exactly finding what I am looking for. I can provide dimensions as needed, but really just looking for a general formula on this. Any help is appreciated. Thanks all.
Edit: I have the ShapeBuilder software, however it won't calculate torsional properties for combined sections, and the drawing tool is not fleshed out enough to create this as one shape easily. I have looked into other software packages, but I have limited access to buying new programs. I can look into any program recommendations/input you provide. Thanks.
