Load bearing lvl beam span tables5/29/2023 ![]() as possible and head to the local lumberyard. If you are dealing with a large opening, say 8ft, or larger, I would gather as much info. Once again, "is there a foundation under that wall" is playing way too loose for my tastes, as there are plenty of examples where this idea can lead to trouble. Typically there is no foundation below that wall, as it it typically supported by a beam, posts, and poured concrete bearing pads. The majority of typical stick framed homes ,with dimensional lumber supporting the floor structure, over a crawl space or basement, have a center bearing wall. Either a Gluelam beam or a made up wood I beam.īut first off figure out if it really is load bearing. Is it an outside wall, a center bearing wall, is it supporting a second floor, a roof, how is the roof framed, snow loads, uniform load or is there an unusual point load above, what are the floor joist spans? And that is just off the top of my head.īut even better than that, talk to your local lumber yard and as them for a wood composite beamof the span you are looking for, tell them the application and they will size it for you, probably chealer than a solid wood beam in any case. Too many unknowns to make a statement like that. Just checking my header sizing table which says a 12 foot opening can be made from a built up beam of 2, 2*12's nailed face to face to make 4*12 beam.

Now how do you know its a load bearing wall for a start? and of course the foundation wall is in good shape. Tou will also NOT need to pour a footing if the hole in the wall is over an existing foundation. You will not need a steel beam either unless you are into very large spans. Of course you will need a tempprary stick wall to hold up the roof trusses or the floor upsairs while you remove the existing wall. When I looked into it it was all pretty simple to frame a built up beam. I am regstered Mechanical engineer so you can bet I'd pull my own teeth out before I wentemploying any engineering help. Your library should have lots of books on house framing. Home Depot used to sell a a book called "House framing". Load bearing walls absolutely do NOT need a structural engineer unless you are doing something way off the beaten path. ![]() ![]() Woah there folks foks before we all get grand and scary!.:) ![]()
