Dynamic Response of the Single-Layer Kiewitt-8 Reticulated Dome Subjected to the Airplane Crash

The dynamic response of large space structures under accidental impact has been the subject of intense research since the occurrence of the 9/11 incident. In the present paper, events of aircraft impact to the single-layer kiewitt-8 reticulated dome were simulated by using the 3D ANSYS/LS-DYNA. Impact loadings were carried out respectively by the Riera force history method and by modeling a real plane similar to Bombardier Challenger 850. Simulation results indicated that the impact by modeling a real plane directly is more reasonable than the method by Riera force history. Furthermore, a series of different impact events were added to investigate the effect of impacting position and the flight attitude of the airplane.
