Blast load conversion -STAAD time history
Blast load conversion -STAAD time history
(OP)
Hi engineers,
Can any one suggest a method for converting the blast pressure into force (Time history)
The Explosion overpressure of 10kn/m2 (0.1 barg) combined with pulse duration of 0.2s.
In STAAD time vs force how to convert the pressure into force.
Size of the frame is 3m x 3m x 8m(height) all columns/beams 250mm sq tube.It is a open steel structure.

RE: Blast load conversion -STAAD time history
Of course, this is a pretty deep topic. With blast loading one of the first questions (for the client) is: what sort of damage are you willing to take? Do you want the structure just to survive without collapsing....or do you want it to come through with it largely intact? The cost difference between the two can be enormous. That question becomes important after the steps I discussed in the previous paragraph because then you get into design.....and then the question becomes: do you go elastic or plastic in your design? So like I said: there is a lot to it. A good book I read on this once had a flow chart to get through it.
I hope this helps.
