How much weight can studs handle?
Inahardplace

Hello all!
I have a house built from 1907 with an addition from 2003. In the addition, I put a half wall that was built around a 120 gallon fish tank. The fish tank itself weighs 300 or so pounds; plus the water (120x8.2=984lb) equals 1200lb+. Now in the half wall, there are aproxamatly 12 5-6' studs screwed into 1' 1/2 rafters which then go into concrete. Would the studs be able to support the force of the fully loaded tank? I will try to post a photo later. Thanks.

Actually a lot.

But even enginieers will have a hard time giving you a precise answer, because there are so many factors: length of the 2x4 or 2x6, type of tree, moisture content, and more.

Believe or not, you should worry more about swaying than simple dead weight.

A stud by itself is proportionally weaker than a stud that's part of a wall system; sheathing and even the drywall work in concert to stabilize each other into a load-bearing system.
Other points to consider is if the load is centered over your wall, or is offset.
Substituting 1/2" smooth plywood (glued and screwed) for the wallboard on your wall will create a "stress-skin panel" that far exceeds a conventional framing job by a significant factor.

I've wondered this myself, mainly because I have 6 packed bookcases in a small home that was build in 1947. It doesn't look like there are many support beams under the floor at all, when I've checked out our small crawlspace. I'm a bit worried that the floor could collapse entirely with a small quake, especially as my wife and I live in an earthquake zone. How do you figure out what is enough support when you have hundreds of pounds of weight on your floor?

if the section of floor with the bookshelves doesnt have a bearing wall directly under the joists supporting them the joists can fail and collapse.

a friend owns a book store and has a room jammed with shelving, hes often wondered the same thing, he may get me to go in some day and quickly put up a wall to support the joists so such a thing doesnt occur

Well, you know how every so often you have to turn the bookshelves over to work out the sag? I suppose you could do the same thing with your floor joists!
