Preliminary analysis of an rc containment structure subjected to aircraft-impact

Analysis of aircraft impact is required for newly designed nuclear power plant containments, that are typically robust reinforced concrete (RC) or prestressed concrete structures. In our paper we shortly summarize the main function of containments and show some typical examples for their structural arrangement. From the point of view of the impact we show the typical effects of an aircraft impact and the analysis methods of it. In the second part of the paper a preliminary analysis for aircraft impact into a prestressed concrete containment building is executed with different methods and with a military jet and a large passenger aircraft. At the end results of the analysis are evaluated and suggestions for more detailed modelling are made.
