If you give him 350, he'll just keep coming back...

There probably is some factor engineers use but I don't know it. I just imagine, on average, it is a surprising amount of weight.
Several variables determine a walls ability to carry a load like intersecting walls.

Using Woodworks Sizer software... ONE 8' tall 2x4 SPF(S)#2 stud can safely carry a live load of 1100# with 1" eccentricity, continuously braced in the weak axis direction.

No stamp, no guarantee. Hire an engineer.

plumb and level would be a factor as well as quality of lumber and fastners.

Then therss always how many and how big of holes the turd herders and sparkys put into the wall......some of the walls I have seen might as well be made with 1x2s

I think it is around 3000 lbs per linear foot of equally distributed down load. Lots of factors involved like point loads and keeping joist within
5" of stud, nailing patter of sheathing and drywall.

Correction #3000 lbs per sq foot which will put a 2x4 wall around 1100 lbs per linear foot equally distributed load. Its been 25 years since I graduated Engineering school so I'm rusty. I still recommend it be engineered so all the variablescan be considered.
