I'm designing a steel framed canopy with HSS 10x10x1/4 columns. The architect wants electrical recepticles recessed into the columns, so the column will have a 4"x4" square hole in one side. I've never come across this situation. I've always seen stuff surface mounted.
What is the failure mode of this column at such a large hole?
