Blast wall design
Blast wall design
(OP)
I have to design a 5 level parking garage for an US airport. The standoff distance between the terminal and garage is less than 300 ft. The only information I have is that, per the post 911 design guidelines, I have to design a blast wall between the garage and the terminal.
Can anyone direct me to the relevant blast design standards/manual,detailed parking standoff distance requirements. Any other info welcome..
Thanks.

Thanks for your promt reply. Here is the info you requested.
I don't want the blast wall to be part of the parking garage. If there are space constraints to install it independantly few feet away from the garage, then the wall could be a part of the garage. The garage is going to be Precast concrete, however the wall could be cast in place.
Further advice is helpful.
Thanks

A few things to consider:
What is the threat level? i.e. How large is the bomb; what type of explosive are you assuming; where will it be placed?
How much damage is the client willing to accept in the event of an explosion. This is something you need to discuss with your client. The more protection they want, the more the structure will cost.
A blast wall may or may not achieve the desired result. The location of the threat with respect to the blast wall is crucial. Depending on where the wall, the shock waves could go right over the wall. In that case the wall didn't serve any purpose.
Even with a blast wall, you need to consider the effects of broken glass/schrapnel from adjacent buildings injuring or killing people.
I think many clients don't fully understand what goes into this type of work. It's more than strucutral design. You might want to consult a firm that deals with this type of work.

I know you intend well. I would not have posted the link for very obvious reasons.
My two cents worth.

I was surprised that the manual was still available on-line. However "Big Brother" must belong to this forum; the link no longer works.
