Blast resistant concrete block walls
Blast resistant concrete block walls
(OP)
Hi All,
I have a project where need to design a 8m high blast resistant masonry wall. All interior walls for the refrigeration plant have to be designed to withstand outward pressure of at least 2.4kpa (50lb/SF) in excess of the design outward pressure of the other refrigeration plant room walls.
Any suggestions what is the best solution and how to design a wall for a blast/explosion,etc?
Thank you
Regards
Karol

If any of the walls are bearing walls, that is another consideration. A roof framing plan of the area requiring blast-proofing would be helpful showing probable locations of blowout panels.

National Academies Press has Protecting Buildings from Bomb Damage: Transfer of Blast-Effects Mitigation Technologies from Military to Civilian Applications http://www.nap.edu/catalog.php?record_id=5021 and Protecting People and Buildings from Terrorism: Technology Transfer for Blast-effects Mitigation http://www.nap.edu/catalog.php?record_id=10230
The Effects of Explosive Blast on Structures & Personnel.pdf not sure where I got that from
Army Corps of Engineers has something similar to TEK 14-21, but I can't find it, but there is this: https://pdc.usace.army.mil/library/tr/06-08

Just for clarification, the refrigeration plant is to be enclosed by two external blow out panels and two internal masonry walls which must resist the blast pressure. The 50psf came from the client, this a tender I am working on.
I wonder if there is any rule of thumb I can use to quickly size the wall or maybe a special restraining system? I assume it would have to be a sort of hollow block reinforced with vertical rebar and tied to a steel frame?

2. If you can't get the dynamic software, there are equivalent static-analysis designs, but they are much more conservative. Go to the Whole Building Design Guide www.wbdg.org and download the UFC's for anti-terrorism/blast resistance. These are also free; the basic UFC blast criteria document is declassified and does not require clearance.

If there are no issues on the budget I suggest that this masonry wall be covered with steel plate on both sides. Certainly these plates could increase the resistant of the masonry from blast.

That's true of almost all of the military and even some government sites.
