Dynamic response of an office building loaded by an explosion-generated air wave

摘要

This paper deals with determining the dynamic response of a standard office building to a nearby explosion due to a charge of explosives typically concealed in a motor vehicle. This particular case concerns the arrival of a truck with a terrorist charge of explosives initiated at some distance from the building. The structure selected for the dynamic analysis is a simple four-storey building with masonry walls and reinforced concrete floors, of a type widely used for administrative purposes. The response of the structure loaded by the pressure wave was computed by the methodology of equivalent static analysis, and a direct dynamic analysis was also made. The results of the two methods are used for a comparison of their information capacity with reference to the actual behaviour of the structure.
