I am making plans to finish my basment and I have an air duct problem. The 5 inch duct runs between the floor joists, then has a 90d down turn, 90d across two joists, then 90d up, the 90d to continue to up to the wall where it turns 90d up to the master br. I would rather not have to box around this duct. I want to cut a hole in the joists and reinforce them with 2X10s with 5in holes in them. Can I do this (by code)? If I can't is there a better way? I wanted to pass the duct between the proper joists but that would mean going thru the part of the return air duct. Any thoughts on this?

Terence: No you cannot do this. If you do, big mistake. Your floor joists keep your home level. It does not take much to get them to sag. Then you have a big cost. I would take a look at them as they are, and ask yourself why did they do it this way.
Because they did it to code. Build a box.
Sorry about that.
