The Pentagon Building Performance Report



P E. Mlakar, D O. Dusenberry, J R. Harris, G A. Haynes, Long Phan, M A. Sozen


Following the September 11 crash at the Pentagon of an airliner commandeered by terorists, the American Society of Civil Engineering established a building performance study team to examine the damaged structure and make recommendations for the future. The members of the team reviewed available information on the structure and the crash loading and drew on focused accessments by others. In addition to analyzing the essential features of column response to impact, they investigated the residual frame capacity and the structural response to the fire. Plausible mechanisms for the response of the structure to the crash were established. Recommendations are offered for future design and construction along with suggestions for research and development. The report is available on the ASCE website:
