摘要

摘要: 为研究复杂结构高层建筑受到飞机撞击后的坍塌过程，使用颗粒流理论对该过程进行模拟，过程包括撞击、爆炸、火灾及建筑坍塌.引入了颗粒流相关模型，包括飞机撞击模型、爆炸模型及火灾模型.建筑模型高为216 m，中部空间较大并由4个核心筒组成的复杂结构.分别在建筑高程200 m和100 m处实施了撞击模拟.其结果显示：由于建筑结构的复杂性和撞击高度不同，导致撞击后建筑破坏过程差异明显，特别是坍塌原因、坍塌形式和坍塌时间差别较大.

Abstract: In order to study the collapse processes of complexstructure highrise 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.
