RESPONSE CHARACTERISTICS OF HIGH RISE REINFORCED CONCRETE BUILDING SUBJECTED TO IMPACT LOAD : Comparison of response due to airplane with earthquake(Structures)

Abstract

Responses of a high rise reinforced concrete building with 20 stories were determined subjected to earthquake and impact load due to collision of Cessna airplane. 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 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.
