Hi,
I am considering making a window/picture cutout as shown in the image in a load bearing wall. This wall is between kitchen and the living room and it is on the first floor. Since there is one story below this floor(basement). what sort of support
do I need once I have removed 3 studs and replaced it with a header. I understand that now header will transfer the load
on the sides and the load now on each sides(2 thick red arrow in the picture) will be more than what was before since we replace 3 stud where load was equally supported by all existing studs.

So in order to compensate, Do I need to provide 2 more post to support in the basement. and if so do I need to dig the concrete floor in the basement to install these 2 supporting post.
Esentially the load remains the same on this wall but by making this sturctural changes I am creating 2 point loads at ends which is different that exisitng wall load distribution where the the load was distributed equally on each stud.


Thanks

I'm not an expert, but adding a window into a wall will not make you need footings under the point loads. That's more for when you tear out the entire wall and add a great deal of weight at the ends of a large beam. I think you should be fine.

You will be fine---I usually add a 2x10 or 2x12 double as a header--that is over kill for a small opening---but it is what I do--saves time--easier to keep the wall flush and it is plenty strong.

Make the window top same elevation as the other house windows, if possible. IF a TJI floor joist system, you will need point-load blocking at the rim joist. Your local AHJ may want to advise as this is a "structural" change... give them a call to be safe. Appears to be under a six foot wide window, doubt you need blocking, depends on the snow load per location...http://publicecodes.cyberregs.com/icod/irc/2009/icod_irc_2009_5_par024.htm
