1. basement beam, span 22.5 feet. No post or column in middle, support at ends only.
2. The floor floor joists span is 26 feet, the widith of the house. They extend two feet over the cinder block basement walls.
3. Roof tresses are factory made. Not sure about the load distribution. The hallway wall on the upper floor is directley above the basement wall we want to remove. I would guess and say it does carry some of the roof load.
4. Pasadena, Maryland
5. Asphalt shingles
6. 2 story basement, upper floor,roof.
Is there any way we can use a W8 beam with the 50ksi? When we lay out the footings for the support posts do the posts need to be in the center? One end of beam will be next to the cynder block wall, so to be centered we would need the new footing to be tied into the existing foundation footing? At the other end the post will be next to an existing king stud, should we excavate under the existing concrete floor to get the footing centered next to the king stud? Can the footings be dug down deeper to reduce the size?
