I plan on renovating the kitchen in my 120 yr old post and beam framed house this winter. I am completely gutting the room, down to the framing. It is single story section of the house, located over a crawl space and attic above that is not used for storage. The main beams are 8"x8", the ceiling rafters are true 2"x4", the floor joists are true 2"x8". I plan on replacing the rafters and joists due to sag, twist, bounce, and shrinkage over the years. My question is, what is the proper way to secure nominal lumber joists and rafters that are wider than my beam? I plan on using at least 2x10 for the floor joists, and my beam is only 8 inches.
