Abstract
Concrete-Filled Aluminium Alloy Tube (CFAAT) column may be damaged by lateral impact. Based on general finite element analysis software, the dynamic analysis and performance of lateral impact of CFAAT columns with different tube wall thickness are studied in this paper. The results show that when the outer diameter of the columns is constant, the impact resistance of the columns can be improved by increasing the thickness of the aluminium alloy (Al alloy) tube, and the reinforcement of the core concrete constraint by increasing the strength and thickness of the Al alloy tube is the main reason for the enhancement of the impact resistance.
