This post might not be exactly what you expecting, given the title and all...
When an array of studs is used as support under major load points, they are just nailed together and need some help.
The help comes in the form of straps. Ideally the straps should be placed high, middle and low. The purpose of the straps is to prevent spreading out of the studs over time as weight and gravity do what they do best.
This is an array under a steel beam in a garage on a recent pre-drywall inspection. The steel beam is visible on top of the array.
You can see that the first attempt just missed by a bit!
The second attempt did get strapped, but with only two. That was not my biggest problem with the job. The strapping should wrap completely around the array and be nailed on each end and into each stud. This will prevent separation. It appears correct, doesn't it?
But what if the studs are not really nailed at all?
What if the nails are into the seams instead?
Now I'm no engineer, but does this seem right to you?
Yeah, not to me either.
On top of it, there were other stud arrays in the house, similarly under major load points, which were not even strapped at all. I know, they should be. ALL stud arrays should be... The supervisor said that it was just my opinion that they need to be strapped. Opinion?
Mother Nature will enforce her laws, with or without our opinions.
If stud arrays aren't strapped, again, over time, weight and gravity will work and settlement will occur as the studs separate inside the walls. Have you been in a recently-built house and seen what appears to be crushed drywall? That is more than likely from an improper structure UNDER that drywall.
My recommendation: Hire a home inspector! Even what might appear to be correct can be caught with an experienced eye and exposed as not correct at all.

Clever title Jay!....
Not my vision of Strapping Studs, yet proof once again that you should ALWAYS get a home inspection!
Best regards,
Judi - sorry to disappoint you! And I agree - always get a home inspection.
I'm with Judi * I was thinking Chippendales and about to brake $100 bill for $1s * NOT Clydesdales!!!
Sorry, Wallace. I am... really...
I was talking about HOLY, um, holey straps nailed TO studs...
Jay - Good eye that could help the owner avoid future problems. I'd imagine the local inspector wouldn't give it a second look.
Rule # 1
Always strap your stud
sorry I had to
enjoy the day
Wow they actually managed to hit every seam. You would almost have to be trying to do it that way.
Mr Jay,
I thought the title said "stapped-in studs" and here I are.
Nutsy
John - that was the builder's position, "The County approved it." That's pure pap. They didn't see it for sure, and still, that doesn't make it right or smart.
Don - or the whole group of them...
Troy - those holes are pre-drilled, so they positioned it that way. 7-11 construction, for sure.
Nutsy - that is a strap, for sure! Or your gear to go have a match with a couple of Ninjas.
My heart fluttered at the subject matter...and alas....a less than perfect stud....no surprise...they're everywhere...darn !
Jay, for some reason I think that array is likely to spread under a heavy load.
S&D - some strong studs there, but for sure they needed to be more strapping.
Jack - methinks the same. There were other arrays indoors, which were not strapped, and were already separating.
Mr Jay,
Mr Charles bought me the outfit and I think it is swell.
Nutsy
Are you saying the suit makes you look like a strapping stud, Nutsy?
There is no excuse for that. Like Troy said, you almost have to be trying to do something like that.
I understand that strap has pre-drilled holes Mike. Why do you suppose that "carpenter" would do such a thing? My answer - he was picked up at 7-11 and doesn't know better. In fact, he might not even understand what the strap is for. He was just told to put it on there!
