Removing 2nd Floor Ceiling Joists
So, before I get started with this one, I'd like to mention that this will ulitimately be designed by a licensed SE. But, this won't occur for some time and I am interested in learning about what I should expect as it will affect some layout that I'm doing for another project.
I have completed the basic design for reconfiguring about 80% of the second floor in my house. The design will require no exterior mods and only minor structural modification (installation of a short L/B beam for a passageway). In the master bedroom, my wife and I would like to remove the existing flat ceiling and create a vaulted ceiling based on the existing roof framing. In that ceiling, we'll be installing either two or three sky lites.
Our house is 100 yrs. old. It is balloon framed and all lumber is old-growth pine. Now I do know that those joists are integral to the roof structure and to simply remove them would tend to make the roof want to collapse. I would also imagine that as installed now, they serve to keep the walls from kicking out as well.
I'm guessing that prior to their removal, some vertical support would probably be needed beneath the ridge line to transfer load. This is probably not too awful since my existing load bearing walls on 1st and 2nd floor are pretty much running beneath/parallel to the ridge line as it stands today. In addition to this, would some sort of lateral ties need to be made between the top plates of the exterior wall and the new bearing wall? I don't see this as too big of a deal if needed since we were already planning on having a couple of exposed built-up beams running the width of the room to hide some small diameter ducts and electrical.
Any thoughts, ideas, etc., are welcome!
