Unique Header Span sizing table needed: Gable wall but with 2 exterior load floors
This is a unique calculation… anyone have header span table for two (2) exterior load bearing walls BUT WITHOUT roof load?
This is for a walkout basement window.
Details:
– Gabled wall (no roof load) and window not under peak.
– Two load bearing walls above (assume two (2) center bearing floors at 28 foot building width)
– Desired window header span = 4′ 3″
– I’d like to use 2-2×6 (with 1/2″ plywood sandwiched), but I suspect I need to go to 2-2×8

Load Beam Chart
You'll have to be able to compute the load per LF on the beam.
It sounds like you'll be carrying part of the floor load. It depends how long the joists are from bearing ponts??
Unique Header Span question
You say that this opening is to be on a gable wall, which is why you state no roof load. Are you sure there's any floor load? The only way a floor loads would get transferred to the gable wall is if the floor joists of both floors above are running perpendicular to the gable wall. More often, the floor joists will be running parallel to the gable wall. Let me know and I can tell what header size you'll need.

Yes, I have the ceiling opened up. At the last ~ 15 feet of the house, the floor joists were rotated 90*. Why? not sure what the thinking was in 1969 when the home was built Perhaps they did this because the basement has low ceiling and 6 foot+ door way on what normally would have been the load-bearing exterior wall.
