Impact response of a high rise reinforced concrete building with 20 stories which was designed in accordance with Japanese seismic design regulations was analyzed by three dimensional elasto-plastic structural model subjected to impact load due to collision of F4 Phantom fighter of middle size. Three collision points were adopted, that is, the higher floor 19, the middle floor 12 and the lower floor 7. The impact load was obtained based on knowledge from the full-scale aircraft impact test and impact velocities for F4 Phantom was selected as three levels. Consequently, the deformation and force due to collision of the fighter with impact velocity of 150m/s was 4 to 10 times than those subjected to collision of Cessna airplane with impact velocity of 111m/s and 1/2 to 1/4 than those due to design seismic waves with level 2 intensity.
