Keywords: Short Column, Crashworthiness, Impact, Buckling and Compression

We simplified model based on the force-deformation relationship of compression impact behavior of the support column under cabin floor, by incorporating the model into the finite element code. Moreover, we propose methods which increase shock absorbing ability of the column members in order to improve crashworthiness of aircraft fuselage structures.
