Verification of the Structural Behaviour
in the Event of an Airplane Impact
Abstract
The structural behaviour in the event of an airplane impact has to be
analysed. The local resistance as well as the global stability has to be verified. The
integrity and functional reliability of all safety related structures and components
has to be guaranteed, including the effects of induced vibrations.
15.1 General
The mechanical actions of an airplane crash on a building can be divided into three
categories:
(a) local loads (resistance to penetration),
(b) global loads (structural and position stability) and
(c) loads of assemblies and components due to induced vibrations (integrity and
functional reliability).
In practice different computational models are used for all three categories in
order to be able to include all the relevant influences and boundary conditions for
the specific verification. It is not possible to discuss all verification procedures as
part of this contribution. Rather only a broad overview will be given here.
The first regulations in Germany for the design of building structures against an
airplane crash were published by the Institut f¨r Bautechnik in 1974 (cf. [
1
]).
Further rules were to be established by the Nuclear Safety Standards Commission
(KTA). Drafts were proposed (cf. [
2
,
3
]) but never adopted as final KTA rules.
Because there have been no plans for new construction projects since the 80s work
was not continued. There are several references to airplane crashes in the current
version of DIN 25449 (cf. [
4
]) such as specifications for the resistance to punching
for impact loads.
