New building concepts protecting against aircraft impact

Aircraft impact is a decisive load case for critical infrastructure as high-rise buildings in prestigious large-scale urban developments or nuclear power plants. The proposed paper introduces new concepts based on high performance concretes (HPC, UHPC) for the example of the 'Security Scraper' [1,2] and an innovative superstructure for existing power plants [3,4]. Key analysis steps using Two-Degree-of-Freedom (TDOF) and finite element (FEM) methods and their experimental validation [5] are used to predict dynamic response on local and global levels to maintain structural integrity under impact and to keep the lire outside the security zone.
