Armory Structure
Armory Structure
(OP)
I am in the process of designing a police station. There is an armory in the design. I know we'll have to use concrete walls right round this. Can you tell me any other factors that I have to consider in designing this? Useful link is appreciated.

RE: Armory Structure
I have seen some with coarse textured block grouted solid to decrease the noise level when the pricy panels are not in the budget.
Depending on the possible use on either side of the walls you could be seeing "high security prison" type construction with steel as close as 8" o.c. There are special block made to permit construcion without any lifting over steel in place. Usually requirement is part of the initial criteria.
If there are concrete slabs, the non-bearing walls may have some very important security connections at the slab above (depending on construction sequence).
You can expect some unique requirements depending on the use of the facility. If it is just administrative/target range/ book 'em and keep them for a short time facity, then not many unusual requirements.
Always an interesting building to plan/design. - I worked with a construction manager/architect of a high security prison and attended the "grand opening" for the influentials and ex-con consultants. - We had the opportunity to spend the night in a cell!

To me, CMU would be a definite no-no due to the tight grid and the relatively low strength of the block.
No strength worries here, eh?

Also, many times you can design into it a blow-off section (say in the roof) that will fail first (on purpose) to direct any blast forces away from personnel.

Is there any publication that provides pressure equivalent for different types of blast or even method of designing the walls, floors, etc.?

This paragraph is taken out of the manual: TM 5-809-6/AFM 88-3, Chap. 6 which is found here:

9-2. Blast-resistant construction
Design of structures to resist the effects of accidental explosions will be in accordance with TM 5-1300/NAVFAC P-397/AFM 88-22. The reference is mandatory for explosive safety design. Design of structures to resist the effects of conventional weapons will be in accordance with TM 5-855-1, and design of facilities to resist the effects of nuclear weapons will be in accordance with TM 5-858-1, TM 5-858-2, TM 5-858-3, TM 5-858-4, TM 5-858-5 and TM 5-858-8. The design of blast-resistant structures must consider the transient loadings and dynamic response of the structure that results from the specified design event. Blast-resistant design is often required in conjunction with the construction of weapons system facilities, both developmental and operational, as well as for structures designed to resist the effects of intentional attack.

Sorry I can't be more specific - it's been a while .... and I've tried to forget it.

There is an Army COE documents or DOD documents out there that explain all this...can't find mine.

If required to resist explosion NFPA has a section on damage limiting construction due to deflagration that will give you design criteria and how to determine resistive/relief forces.
Ask your architect to review the code for you, but do it yourself as a good check against liability.
