Design of Vaults
Design of Vaults
(OP)
Dear all,
Can one of you help me to solve the following problem?
I'm designing a 3 storeyed bank building. There is a vault on the 1st floor level. I thought of having 9" thick concrete walls around the vault. Is there any other considerations when you design these type of structures? If you could provide me with a web-link (if available), that would be ideal.

The recent bank structures that I have worked on utilized a pre-manufactured vault wall and ceiling. The floor was recommended by the vault wall supplier and constructed by the general contractor (concrete sub). The latest recommendation that I used was (3) mats of steel with reinforcing in each direction and 12" minimum concrete thickness. This wault was elevated above the basement. There is some coordination to be done between the vault wall supplier and vault floor dealing with connections/support.

One low tech, but effective way to prolong break through from this means of attack is to insert staggered layers of expanded polystyrene boards within the thick concrete walls. The EPS boards serves to foul and gum-up the tips of these burn bars to such an extent that it greatly delays burn through, hopefully allowing the authorities to arrive in time to save the day!

Either get a premanufactured vault or a consultant that is specialized in this area.
FYI: All bank vaults can be broken into, they're just something gives law enforcement time to get to the scene. Better vaults take longer to get into, etc.

I,ve only worked on one bank valult. The requirements were for 3 layers of staggered #8 bars. I don't remember the exact spacing but I think it was 3" oc or less. The requirement was based on the maximum drill size. Above that size the bar spacing was such that you could not drill through the wall with out hitting a rebar.

As far as bars go... did some work on a jail once and the main entrance had a floor to ceiling wall of bars... 1" dia through 3/8" straps with four lines of weld dribbled on the bars to keep from sliding the straps down the bar... the whole wall was secured at the ceiling with three 3/8" lag bolts... Ho Hum...

I did some surfing on "Atomic Hydrogen Torch". It generates a temperature in excess of 3,500 degree Centrigrade. (Diamond Evaporates, Titanium melts) .......
Hope not many people have access to these kinds of products!
