Abstract：In the event of aircraft impacting on a containment structure, the coupling effect of the impact load and the explosion load caused by the aviation oil needs to be considered. Recent studies mainly focus on the effect of single impact load, however few analysis and comparisons of the coupling effect are presented. In order to study the dynamic response of containment structure subjected to the coupling effect and propose a feasible numerical model, a coupling analysis of the whole accident process is carried out based on the refined dynamic numerical model of the aircraft and the containment. The analysis firstly uses the TNO (The Netherlands Organization) multi-energy method for vapor cloud explosion to quantitatively represent the aviation oil explosion load. Then, the applicability of RHT constitutive model under different load types is verified based on the numerical model test of reinforced concrete slab anti-explosion and anti-missile impact. Finally, the refined numerical models of the A340-300 large commercial aircraft and the fourth-generation nuclear reactor containment are used to compare and analyze the displacement time history and damage distribution of the containment under the single load and the coupled impact-explosion load. The results show that it is very important to analyze the effect of the coupled impact-explosion load in the safety evaluation when the containment is impacted by an aircraft. Based on the model of this paper, the peak displacement under the coupled load is about 27 % higher than that under the single load. Besides, the local damage characteristics of the containment also have a relatively large change. Compared with the single impact load, the coupled load increases the damage area by about 142 % in the fuselage impact area and by about 72.8 % in the engine impact area, and the degree of damage in the local area where the engine impacts is greatly increased.
