Assessment of Structural Steel From the World Trade Center Towers. Part III: Physical Damage Caused by Impact of Aircraft
Stephen W. Banovic, Timothy J. Foecke, Frank W. Gayle
This paper describes damage characteristics and failure modes of the recovered structural steel components from WTC 1 and WTC 2. Knowledge of damage to the steel elements played an important role in the investigation by ascertaining the response of the structural steel of the towers to the impact of the planes and providing information on perimeter column damage for correlations with impact damage modeled in the baseline structural performance and aircraft impact damage analysis. Results focus on the five exterior panel sections in the impact zone of WTC 1 and the four core columns from near the impact zones of WTC1 and WTC 2.
