Interior Load-Bearing Wall under W-Truss Roof ??
Comments (5)I doubt any residential property with trusses has any interior load bearing walks both outside walks are load bearing. And I'd say all commercial building with trusses wjth interior walks are definitely load bearing not residential . Me I would treat it as a load bearing wall building 2 posts Anda large beam the span of the wall to be removed . Or better build two walks the. Height of the wall to be removed and 3 foot longer with studs 3 foot o.c on center first then remove the wall. If I seen it . I'd know in a minute if it was. But I seriously doubt it is with house trusses only your exterior walls that run the length of the home are load bearing . W trusses . If the home has floor joists on a second floor that's the only time it would be load bearing.......See Moreexposing roof trusses to open up ceiling?
Comments (30)I figure after demo part I’d just need to do the insulation between rafters.. then cover with drywall, plaster, paint.. ? Have you been to the attic? Got any wiring up there? Any ductwork? Any plumbing vents? What is your plan to vent the roof? How are you going to insulate? What R value will you have? How do you plan to brace the trusses? What about climate control--HVAC? You will be adding a lot of cubic feet of new space that, in all likelihood, your HVAC system isn't designed to handle. Not only additional cubic feet but also the problem of stratification. How & to what do you plan to fasten the new drywall? You can't fasten drywall into the side of the truss; you will have to install some nailers/ ledgers to fasten drywall to. Trusses are typically constructed of 2 x 4's. Of particular note, the top chord is a 2x4, meaning there will be 3.5" between the roof deck and the bottom of that chord. Which will be buried in insulation. So, you need to realize that you will not see that top chord from the room below. What is you plan to deal with/ cover the gaps in the drywall caused by the trusses themselves? IOW's, what you want to do is a good deal more complicated and labor intensive than what I *think* you are thinking it will be....See Moreneed help with roof truss
Comments (32)Take a closer look at the photos. The existing structure is, in fact, a very simple truss but only because the rafter chords sit on the ties just beyond the wall plates instead of directly on the plates. If the rafters did rest on the top plates, the ties could simply be raised until the rafters reached their maximum bending capacity (about 6" by the IRC tables with assumptions listed earlier). Figuring out how to efficiently raise the ties to the mid point of the barely adequate rafters and repair the rafter seat detail has been discussed at length earlier. I have attempted to give the OP sound structural advice within the parameters I listed because that is what I have been trained to do. If there is no building department oversight and he is willing to tolerate sag in the rafters and movement in the wall top plates during extended snow storms, all he needs to do is block or strap the rafter bottoms to the plates and then raise the ties. However, all it would take under full loading conditions is for enough tie connections to fail and the shed could collapse. In my opinion, the tie connection overlap is too small for adequate nailing or bolting and should have a metal or wood plate. Potential structural failure is not an option I would recommend even for a shed....See MoreShould I fasten my addition’s new roof trusses to the existing framing
Comments (5)Personally, I'd say yes, but unless you're not an engineer you should ask someone who works in the field. As others already told you here you should consult the building plans. It can indeed make the movement more difficult, but I guess it's better to be safe than sorry. Once I wanted to do something similar but I ended up breaking the roof trussers and I decided to never do this on my own again. It's much better to take advice from someone experienced such asFasteners Suppliers in India or wherever you're from. Also, the material that the cottage it's made from is very, very important. If it's a 'light' wood it can easily break if you try to fasten the addition. Better ask for a professional opinion....See MoreEnrique Nieves
