Abstract

To study damage characteristics of the shield building for nuclear power plant subjected to a large commercial aircraft impact, finite element models for Boeing 767 commercial aircraft impacting on a shield building made of steel-concrete-steel sandwich panels are established to simulate the impact process. The following results were achieved: the aircraft's axial mesh size greatly influences the impact force; some parts of the shield building hit by the aircraft undergo significant deformations while the deformation is smaller in the other parts; the impact velocity has little effect on the impact duration but a great effect on the structural response displacement, and the total impact force rapidly declines with the impact velocity decreasing. The impact force arising from different parts of the aircraft hitting the shield building are given, the simplified curve and the load area of different impact forces are obtained, which will contribute to the determination of the impact force distribution form, thus providing a positive help to the engineering design of shield buildings.
