star shaped brackets
Anyone know what those little star shaped brackets are on brick buildings? I was taking a walk around an older neighborhood here today and saw several old masonry houses with little star shaped brackets on the outside wall between 1st and 2nd floor. At first i thought they were decorative but then figured they must serve some kind of purpose considering they were located in middle of the wall on every house.
Is it something that ties the floors to the wall? Anyone know?

Re: star shaped brackets
They are usually holding the brick wall in - evidence of structural problems. Very common here in Philadelphia.

I do not think they are necessarily evidence of structural problems. The building may have been built like that. They are usually connected to Iron rod maybe with turnbuckle for tension. Similar purpose as ceiling joist.

In areas prone to earthquakes those devices are added to protect unreinforced masonry structures in the event of an earthquake.

Fairly common around here in older 2-4 flat brick buildings built in the late 20's, early 30's. As someone else mentioned, they are tied to steel rods that go through to the other side with a turnbuckle somewhere along the length.
My old 2 flat had 2 on the second floor and below parapet.

Re: star shaped brackets
That's the reason they are there, to provide tension pulling the walls together. Typically they run from one wall, through the building, to the opposite wall.
The reason for the reason they are there, though, could be "any of the above" reasons given.
All the ones I've seen 'were added after the fact' to hold things together when the structures moved and began separating.
That does not mean, however, that some were not designed with them originally.
Original or added? Depends.
Regardless, though, the reason they are there is the same - to hold things together under tension. Think of it as primitive post-tensioning.

Re: star shaped brackets
I haven't drilled into and broke a post-tension cable but I've hung up a many drilled bits onto the sides of them doing termite work.
Several bits I've had to take a cutting torch and cut them off at the edge of the foundation. $150. bits used for extra reinforcement you might say.

Re: star shaped brackets
I used to know their exact names. Dang, this is going to bother me.
But basically everything already mentioned is correct. They are normally used, as Jerry said, after the fact in "ordinary construction" [Type III] to tie the front and rear masonry walls from falling outward. I have seen them on the sides of buildings (at the end of a row). They're very, very common in old Texas town squares and since we don't have many earthquakes (Scott, don't send an earthquake link), I've always assumed they are just there to keep the wall from falling on me as I look up them. I've seen all sorts of shapes (hearts, moons, circles, S, stars, diamonds and lucky clovers -- oh wait, that's a breakfast cereal)
Being a plethora of useless info, anyone else need something while I've got my brain fired up?
