Mechanical and Metallurgical Analysis of Structural Steel (Draft)
Summary:
This report is an overview of the mechanical and metallurgical
analysis of structural steel from the WTC, part of the
National Institute of Standards and Technology (NIST)
Investigation of the WTC disaster.
The purpose was to analyze structural steel available
from WTC 1, 2, and 7 to determine the metallurgical and
mechanical properties and quality of the metal, weldments,
and connections, and provide these data to
other part of the NIST WTC Investigation for insertion
into models of building performance. The analysis focused
on steel from the towers to provide data for modeling
building performance and characterizing the steel quality.
In addition, the steel used in the construction of WTC
7 is described based solely on data from the literature,
because no steel from the building was recovered.
The three goals were to:
1. Determine mechanical properties of WTC structural steel,
Determine the quality of the steel and if it met its design
requirements, and
Analyze and provide insight into failure mechanisms for
guiding the development of models of building performance
and validating their output.
