In this paper, the crushing behaviour of hexagonal thin-walled tube with partition plates subjected to axial compression is studied by using finite element method. It is found that, in the crushing process, the folds, which generate along the full length of tube, come to be crushed simultaneously and the compressive load will not descend, since the compressive force produced in the core part does not descend with the folds forming on side walls. Therefore, in order to press down fluctuation of the compression stress in crushing of tube and to raise its average compression stress, it is a expectable method introduce angle parts, especially 3-fold crossing angle parts, in the geometry of the thin-walled tube.
