Aircraft crash/impact loading on concrete structures

[CNCLLC]

My firm has just been retained to design a small concrete structure that will need to be capable of withstanding an impact from a small aircraft. Is there any information or possible a simplified method to design the concrete elements without getting into a long drawn out finite element analysis?

I think FEMA or US Artmy has some articles on this.

As a matter of fact - search these forums - it comes up from time to time.

Homeland Security too.

You don't need FE analysis you can use single degree of freedom system for modelling concrete elements
softwear like SBEDS can do the job

one issue i think you're going to have is shape and construction, unless someone has analyzed the impact of a kinetic and explosive force on a wall xft thick, made of xyz 'crete and abc lbs of rebar (unless there is a standard wall construction ??).

are you going to test it ?

how are you going to prove it ??

Your client needs to tell you what constitutes a small aircraft, or pay you to retain a security consultant who can come up with the size acceptable to the client.

You need that information before you can design anything.

NRC used to require that containment structures be designed for a 707 crashing into them. They must have a criteria. I'm sure you could scale down the kinetic energy for a smaller plane.

CNCLLC,
Don’t mean to be pedantic, but I hope your scope is “design the building to avoid complete collapse in the event of an impact of an airplane” or similar. You can simulate this by removing a few columns systematically from your system, how many columns depends on the size/speed/weight of the airplane, which should be supplied by the client.
