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 Cessna airplane.Three collision points were adopted,that is,the higher floor I9,the middle floor 12 and the lower floor 7.The impact load was obtained based on knowledge from the foil-scale aircraft impact test and impact velocities for Cessna was selected as two levels. Consequently, the deformation and force due to collision of Cessna airplane with impact velocity of 400km/h was 1/10 to 1/30 those subjected to design seismic waves and therefore it was proved that the collapse of the building would not occur.
