I've found this document from CSI SAFE software, set out the procedure to calculate

punching shear stress that involves unbalanced moments.

but it has limitations that the shape of the critical punching sections has to be parallel to X or Y axis.

What is the procedure that you would follow to calculate the maximum punching shear stress for a circular shape or a shape that has an edge not parallel to X or y-axis?

Thank you in advance.
