Removal of a load bearing wall

Removal of a load bearing wall

Removal of a load bearing wall

(OP)
I want to remove part of a load bearing wall (11 ft span) in a single story home (1969).  The roof is a purlin roof and the purlin braces do not run into this wall.  The wall supports ceiling joists (15 foot span on one side and 10 on the other).

I need to know two things, first, the size of the header required..although I think I have that part.  More importantly, where the jack stud hits the floor, I need to know what to do.

The house is built on 4X6 beams spaced 4 ft apart.  These beams run parallel to the wall beaing removed.  There are pier blocks every 6 ft under the beams.  The sub floor (2x6 t&g) rest directly on the beams.  The jack stud under the header will fall 6 inches to the side of a beam and 2 ft along the beam from a pier.

Is this sufficient to handle this load which should be minimal or is an additional support under the house required?

RE: Removal of a load bearing wall

Sounds like your header isnt carryng much load except 12'6" worth of ceiling (no attic above?).  Therefore, your post loads are not much, but still provide some sort of solid bearing for them.  Do not rest your jack studs on 2x6 t&g alone.  Minimal solid block between 4x6 beams under the jack studs, then check your 4x6 for the additional load.

RE: Removal of a load bearing wall

It sounds like the bearing wall is parallel to one of the 4x6 floor beams, but not on it. That's sort of wierd.

mech PE...I agree with pylko and add one other comment.  You need to establish provision for uplift in your jack stud connection at the bottom and provide a continuous tensile load path from foundation through roof.  This was likely not done at the time the house was constructed, as codes in 1969 did not sufficiently address this issue for wood framing.
