I am wanting to remove an existing load bearing wall the separates my dining room and family room. Can anyone tell me what size LVL I will need for a 28 ft span. The only load on this wall is the roof. There has no second floor nor do i use the attic for storage.
6 18" LVL's through bolted at 3, 6,9, 12, and 15 inches with stainless rod every 12 lengthwise.
No really nobody can give you an answer without knowing your location, and how your existing structure is framed. And its not just taking walls out and putting an LVL in either. That load has to transfer somewhere and that spot also has to be adequately framed and supported at the bottom as well. The safest thing for you to do is get a structural engineer on site.
