Written by a team of ASCE volunteers, this building performance study examines the structural performance of the Pentagon upon the impact of a hijacked commercial airliner in September 2001. The report offers a detailed analysis of the response of spirally reinforced columns to the impact, and the nature of the damage caused by ensuing fire. Numerous color photographs are provided, but no index. Annotation (c) Book News, Inc., Portland, OR (booknews.com)
