While we're on the subject - let me toss out my similar question.
I have a question I hope you can answer. I have a 1926 built, 2 story home in Villa Park (with a full basement)
Currently, I have a wooden beam that supports the first floor. This beam is 8" x 6" (6" tall 8" wide). It runs approximately 35 feet. It is supported by the chimney and foundation on the ends and has 3 support columns placed approximately 8 feet apart along with a load carrying wall near the chimney..
My first concern is that the beam, although not broken, does have a lot of horizontal checking and cracking.
My second concern is that I would like to remove 2 of the three support posts to allow better use of the basement space.
My question is this. What can I do to strengthen the beam so that first, it's safe and second, I can remove the 2 support poles closest to the foundation?
I am sure I could replace the beam with a steel beam, but would prefer instead to reinforce the beam with wood products if possible. (installation and fabrication costs are my concern here) My thinking is that I could sister several 2x8 dimension lumber or perhaps Parralam or LVL beams onto the existing beam. If I could keep the height of the additional beams to 8" I would be quite happy.
This is a preliminary question. Ultimately I would need drawings to get a permit to accomplish this, but I am first interested in figuring out what I would need to do so I can determine if it would be cost effective.
