飞机撞击复杂结构建筑全过程模拟与研究
摘要
In order to study the collapse processes of complexstructure highrise buildings after aircraft impacts, with the particle flow theory the whole process including impact, explosion, combustion and structure collapse was simulated. The particle flow models were introduced into different steps in the forms of the crash model, the explosion model and the combustion model. A building model of a 216 m height, a large atrium and a complex structure composed of 4 core tubes was established. The impact heights were 200 m and 100 m, respectively. The results show that, mainly due to the complexity of the structure and different impact heights, distinctly different failure processes after aircraft impacts are to come, especially in the aspects of the collapse cause, the collapse mode and the collapse time.
