COST FOR AIRCRAFT IMPACT DESIGN OF CONCRETE PROTECTIVE STRUCTURES

Structures for storage of hazardous materials and, more general, buildings and structures that accommodate risk-bearing activities, like nuclear power plants and storage of LNG and LPG, should be able to resist the impact caused by and aircraft crash. In this contribution of the probability of aircraft crashes is discussed. For different type of aeroplanes, ranging from small jetfighters to large passenger planes, the force-time diagrams are shown. For four types of jetfighters the required thickness of a concrete protective structure to withstand the impact of these planes was investigated. The extra costs of an aircraft impact design are determined. These extra costs are compared with the cost of catastrophic accidents. By comparing additional building costs and potential costs in case of a catastrophic impact load it is made plausible that concrete protective structures are cost effective components of advanced protective systems.
