The purpose of our study consists in the research of new ways of calculating the induced vibrations in reinforced concrete structures submitted to commercial aircraft impact. The cutoff frequency for this type of loading is typically within the 40 to 100 Hz range, which would be refered to as the medium frequency range [HER05]. The determination of the shaking induced by an aircraft impact on an industrial structure requires dynamic studies. The response, especially during the transient stage, by using classical finite element method associated with explicit numerical schemes requires calculations with an important calculation time. Also this kind of calculation requires several load cases to be analyzed to consider a wide range of scenarios. By the way, the medium frequency has to be appropriately considered therefore the mesh has to be very refined and consequently, a refined time discretization.
