Blast Resistant RC structure design?
(OP)
dear All,
I need to design blast resistant RC wall for air compressor unit, there is not any flamable liquid or gases nearby that may trigger fire another explosion, can you give me an entrypoint on which code that I need to fullfill.
Regards,

Hopefully your threat catches the attention of CELinOttowa's attention. He's a bit of a blast wiz.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I know that this topic on itself worth thomes of books, but at least I need to provide on what premise I'm designing and I must meet base design criteria. Talking from experience as I worked as CM there wasn't anything additional we do (nor the designer foresee ) for the air compressors units other than steel facade.

Thank you all for the valuable inputs and entrypoints, pointing out that UFC 3-340-02 is valid for blast design criteria was really helpfull. Runing a quick eye through the chapters, one thing is still obscure to me. After finding location oriented parameters such as l/L, h/H, L/H, Za and reading the Average Peak Reflected Pressure (Pr) from figures, should I apply that load as uniform load to structure or is there any other process I have go through?
If I should stick with applying the Pr directly to structure then its quite conservative IMHO, one can easily achieve in close-in range 1000psi values for (Pr). My structure is: "L" shaped wall, I can't even think how it can sustain the stability checks e.g. overturn, sliding etc.. with such a heavy load,
Your comments will be appreciated,

For the record: will this blast occur in a enclosed room or just adjacent to a wall in a open area? What's the equivalent poundage in TNT?

The nature and duration of the blast are important to the structure and its response. An exploding gas acts differently than something like TNT. Determining the pressure and duration of your kind of blast is probably quite a specialized function. I'm not sure what you mean by "geyser".
To apply the side-on (or worse, the reflected) pressure as a static force is very, very conservative. Depending on the nature of the blast and the response, most structures absorb the blast energy and see an effect much less than the static equivalent. You will need to consult with a specialist if you really want to get a best guess as to your structure's response.
