There is a Blast-resistant structures listservice at:
http://64.119.172.143/mailman/listinfo/blast_structuralist.net and a
discussion Bulletin Board Forum located at:
http://www.structuralist.net/prof_bbs/index.php?board=23

There are others with interest in Blast resistant design that may help
you. I recommend the Listservice as the discussion Bulletin Board forum
is not very active at this time.

Don't take offense, but if you're thinking design of shipboard
structures 
is like building design, you're in for a couple of surprises. Ship hulls

and decks are plate structures and fairly soft, and vibration is always
a 
big concern. Things also get tossed around a bit so lateral
accelerations 
are also a consideration. 

Blast loading comprises a momentary overpressure, maybe 2-3 psi which 
resembles gust loading. Presumably you're doing this for a naval ship,
so 
you might want to check Navy requirements for the loading, since some of

the requirements involve high laterial accelerations. If you are doing 
this for a military project, you might want to be aware that
telegraphing 
it worldwide on the Internet may make your supervision or client
somewhat 
nervous.
