So I have this bunch of rebar, and it's in this concrete and we put a big load on it and it's handling all that tension, but there's also this desire of that rebar to buckle all by itself, even without thinking of the overall column with all the concrete, so if these are near the exterior, there's not that much concrete to hold it in place, and so if I have a big load on that and it's starting to sort of push to the side, it's putting that steel into tension, if I have a big load on this column and I'm pushing down on it, whether it's in compression or in tension, there's a chance that that reinforcing bar is gonna wanna just buckle on out so one of the ways that we deal with that from a reinforcing standpoint is we do a kind of wrap, and I'm gonna show on this one a continuous spiral wrap, and that's just gonna literally go right all around, all the way down, and then it would wrap around by, eventually getting down, et cetera, et cetera, and what that spiral is gonna do is it's gonna help hold in that rebar from wanting to buckle towards the outside. It's gonna give that concrete, that wrapping around it, just a little bit of help, to help keep that rebar from wanting to bust out of the concrete, and then we would, in this round situation, we would have some sort of form work, maybe a Sonotube, something like that, that we'd place over this and we'd fill the whole thing with concrete after we placed this rebar cage in there. Do we always do it with a continuous spiral system?
