I have a single story ranch and am doing a reno by myself as a long-term project. Originally, the home was a small cabin and later it was expanded with addition.
The wall that I need to remove supports roof trusses which were originally part of the original cabin's roof. Left and right walls sit on the concrete perimeter foundation wall.
The span is 19ft and I am thinking about using 3x12" LVLs for this purpose (http://www.menards.com/main/storeitem.html?iid=1444438525506). I would love if someone could help me to determine if this is sufficient and I am interested in math, not in advice to hire an engineer.
