its that sheet metal they die cut louvers in and pull apart leaving a diamond shape opening. It may not be the best choice above grade, but a heavy gauge of it in a pour vertically to protect from a tornado missile is what i am after, i have seen the poor shear strength of a lot of walls and would try to strengthen that aspect, but even 12" oc #4 rebar wouldnt do what i want orifice wise. Structural steel could help prevent collapse of the roofing structure. I know F2 suggestions for shelters include 3/4 plywood for impact absorption on either side of 1/4 plate steel for toughness. You might see steel simply gone if it wasnt attached to the earth well, and you might see it bent after a big Tornado. You just dont often see heavier steel torn though, and thats a big key for me.What is expanded metal Limp? Any other names it goes by?
OK, up here we use that to form shutoffs and such. NEVER for added strength in a pour. It can really do nothing that isn't being done by the rebar. The minimum wall pour i've ever seen is 8" thick. I know tornados are strong, but a projectile through 8 to 12" of concrete? I just don't think so. If anything could make it through that, the mesh isn't going to do anything the concrete itself wasn't already. A steel roof structure like what i've seen built could withstand basically any storm, it's the decking that would go. The structural (if we're talking I-beam construction) should be fine. So long as you're inside of that structure you shouldn't have to worry about being decapitated by the steel decking. Myself, if I were that worried about it i'd just have a concrete roof.its that sheet metal they die cut louvers in and pull apart leaving a diamond shape opening.

Generally foundations are dug down to undisturbed soil. Soil testing done by civil engineers will determine if the soil can carry all intended loads including live loads such as snow, wind, etc... the footings and foundation are designed by an engineer based on the soil findings, bearing points in said structure, etc... That said, you're correct in assuming that structures settle. It's pretty much a sure thing that any structure is going to settle/heave even if only fractionally and over time. That does not mean that there has to be cracking though. There are products and methods out there to account for such movement. Skyscrapers move more than the average person wants to know. Those methods and products are not all 100% full proof, but unless you're driving pilings down to bedrock it's what you get and even if you drove pilings to bedrock when tectonic plates touch your structure will move. I know, that's a bit overboard, but hopefully i'm making my point. The soil a structure is built on combined with the design of the foundation and the back fill will pretty much keep a structure firmly in it's place to the point where in an average persons life they wont actually notice any settling if done correctly.And Limp, what would you guess it would take to stop a 300mph wind with chunks of debris in it?
Given the weight of 27 cubic feet of concrete, I would think my shovel and I were outmatched. I might consider getting my 3 bag mixer out of the shed to help, but too much weight and it trips its thermal breaker. Plus one thing I learned doing some homeowner work is that the soil and foundation surely must be in a particular condition of compaction or the whole shebang will settle, surely inviting some cracking. I dont think my plate compactor is gonna get'r dun so my mind was wondering off toward a hyster vibrating calcium filled drum as it was the last large compacting machine I was ever around. I kinda got the impression that a few folks with that kinda gear might be involved. I thought I might paint it though. If thats ok with you.
It will probably just turn out that a poured shell is too big for the wind load and the thing gets turned into a smaller, infinitely denser structure with a base of weight stuck down into the earth that weighs an unreasonably large amount of tons to prevent it from being plucked from the earth. Too bad the big storms can toss locomotives eh? The entry door design is two L shapes to prevent shrapnel entry even if the door is removed. Im kinda fiquring the costs of that are so high that a below grade shelter is what I would end up with, and a lifetime supply of bug spray for the scorpions and black widows.
As for what it would take to stop a 300mph chunk of debris i'll answer like this... try to shoot a bullet through 8" of concrete and let me know how it works out.
