Abstract

This paper describes damage characteristics and failure modes of the recovered structural steel components from the World Trade Center (WTC) towers 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 by providing information on exterior 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 region of WTC 1 and the four core columns from near the impact regions of WTC 1 and WTC 2.
