Several people have already mentioned the two ASCE design guides which
cover blast resistant door design. I just want to mention that in addition
to the structural analysis and design, you might also want to consider
If you must rely on the door to remain operable after a blast, you should
consider how the manufacturer intends to meet this requirement. Some
manufacturers design their doors, including hardware, to remain elastic
which theoretically implies the door will operate and not jam after a
blast. Some manufacturers back up their structural designs and claims of
post-blast operability with dynamic test data. I am not saying the elastic
design approach is inadequate. I am simply saying blast tests, if done
properly, increase the confidence that the product will work as intended
which should be worth something.

We have specified the following for the design of Blast resistant Doors.
1. An incident over pressure of 175 KN/M2 and a time duration of 30 ms
2. An incident over pressure of 100 KN/M2 and a time duration of 50ms
3. An incident over pressure of 30 KN/M2 and a time duration of 100ms.
The contractor has submitted design calculations only for the max.incident
over pressure neglecting the time duration and cases 2 & 3. He has
mentioned the ASCE as the basis of design.
WOuld you inform ASCE has specified any design guidelines for the design
of Blast Resistant Doors. If so, in which chapter?
Also please inform any other code which provides step by step approach for
the design of Blast Resistant Doors. I understand from your earlier
correspondences that Chapter 6 of NAVFAC Design Manual 2.08 provides
guidelines for the design. If you can send me the above said design or its
latest edition will be of help to me.
