What is the maximum span for 2x8 joists?
Our house has 2x10 joists under the 1st floor, 2x8s under the 2nd, and 2x6s under the 3rd (all rough sized). The same wall runs perpendicular to the joists on all 3 floors, but not the basement. I'm trying to figure out whether this is a load bearing wall. The span where the joists meet the staircase is approximately 13 ft, and where they run across the entire house is approximately 16 feet. They are one piece running the whole way. What is the typical maximum span for 2x8s? Is there a way to ascertain whether or not this is load bearing without an expensive engineering consultation?
