bank vault

[pattontom]

How many have worked or experienced on designing structural for bank vault (or similar)? How heavy is the entire setup (for say 2 meter by 1.5 meter room and 8 feet high)? any reference or web site that details this? I need to know how the slabs are reinforced to support bank vault and whether it is safe to do it above a foundation footing portion or beside it (I'm concerned of the reactions). Thank you

Contact the vault manufacturer for the weight. Is your vault a modular structure to be placed within a building or a just door & frame?

If it's a modular structure you're just looking a foundation design. I've designed pads for modular structures - containing pumps and generators - no big deal. The manufacturer provides to anchorage design.

If your building say a CIP concrete vault & installing a frame and door, you need to talk to your client about how robust the structure needs to be; do they want the walls to be blast proof?

I would also suggest you review ASTM F-1090 Standard Classification for Bank and Mercantile Vault Construction and ASTM F1247 - 89(2011) Standard Specification for Intrusion Resistant Generic Vault Structures.

Here's the thing. I'm designing structure for a client who would lease it to banks.. but so far... no contracts with any yet. Now the problem is the layout of the lot is almost fill with foundation footings. So the slabs and vault design would come in the future... now can they just put it on top of existing foundation footings? I'm concerned of the reactions hence right now I need to know how to integrate it with the foundation.

How are you going to get the vault in after the building is up?

In any case, call a vault manufacturer and ask how much the thing will weigh; then put your foundation in now.

The vault is not one solid thing. Only the vault door will be brought in, the vault, walls floor, ceiling or vault room would be built inside. But this is a year after construction after the space is leased out. Now I have to anticipate the slabs footings or supports that can hold the weight of the future vault. Please see the following pic. The blue are combined foundating footings, the red is the position of the vault. Any reactions like torsions or soil reactions or unexpected problem that can result from this?

You are not talking about significant weight in building terms, or significant area for the owner's costs. Put a mildly reinforced slab under the whole area and it will carry more than anyone will ever be able to get into the building. If the soil is only fair & can carry 120 kPa, your 3x6 m (guessing at the size you show) vault would have to be 5M thick concrete on the whole area to load the soil to the max. Presumably the prospective client will want to save some interior volume to rent out to their clients and won't build a solid concrete "vault" 2 storeys high.

If you have to build it later and you don't know much about it, then design it later. Looks like it will be in a slab on grade area between your footings, so you will just need to sawcut the slab on grade for placement of the vault floor slab. Casting the vault roof may be an issue if headroom is limited. Many banks require their own specification for vault construction, including thickness, grade of concrete, and reinforcement. Some require three layer of reinforcement.

To answer your question probably not; but you need to get the anticipated vault loads and evaluate.

The vault floor may have to be fairly elaborate. I recently did one for a bank and the slab was 18" thick (required per ASTM Specification) and the top of the vault slab had to be 3" below the finished floor to receive the vault walls (required by vault manufacturer (some do and some don't)). The reinforcing consisted of 4 layers of bars running each way spaced not more than 4" c-c and there could not be a gap of more than 2" between horizontally between bars in adjacent layers. The vault was installed after the building was up but we poured the vault floor at the time of the building foundation.

The point I am getting at is it may be necessary to saw cut the floor slab and then pour the required valut slab in the future or ideally find out what the requirements are for the slab now and then build the necessary slab.

dig1... did you design separate vault columns for the vault wall/room? I know the vault to be built in future must not be put beside an existing building column because it can affect the response of the moment frame in case of lateral shaking.

 

[hokie66]

You don't need columns for a vault. You have a floor, 4 walls, and a roof.

The 1501 and 999 mm dimensions look kind of ...
How'd you get those numbers?

The building was completely separate from the vault (no columns for the valut, just 4 walls and a roof). The structure was single story and was cold form stud shear walls. There was a gap between the vault wall and the shear wall on one side but I don't remeber the details of how big/why/etc.

Some of the new vaults are a modular construction and are brought in as prefab slab sections and then welded together. I was visiting one of the big banking equipment mfg. and they said that the modular vaults are popular because it allows a "storefront" bank, which is what I think your client is thinking. these sections were very engineered, with a lot of different layers to prevent 'penetration', but they were not horribly heavy, I was surprised that the weight was so low.
contact a couple of the big banking mfg. and get their info, rather than relying on us.
