Dr. Leroy Hulsey, chair of the Civil and Environmental Engineering Department at the University of Alaska Fairbanks (UAF), is now 18 months into his two-year computer modeling study on the collapse of World Trade Center Building 7 (WTC 7).
Dr. Hulsey first announced his preliminary findings at the Justice In Focus conference in New York City on September 10 and 11 — where he stated categorically that there was “zero” probability that WTC 7 collapsed due to the fires it experienced on 9/11.
Since then, he has given two more presentations. The first was on September 29 to the UAF student chapter of the American Society of Civil Engineers (ASCE). The second was on October 19 to the Fairbanks Branch of the ASCE (where Dr. Hulsey previously served as president). We enthusiastically invite you to watch these presentations and the Q&As that follow, which provide a stimulating glimpse into how the engineering community may respond to Dr. Hulsey’s groundbreaking research when his findings are released next year.
As Dr. Hulsey explains in the presentations, he and his team will exhaustively examine other conceivable scenarios that may have led to collapse over the final six months of the study. They will also study the building’s response to losing individual columns and will attempt to simulate the kinds of failures that would be required to bring the building down in the manner observed on 9/11. After their final report has been published, Dr. Hulsey will begin submitting his findings to leading engineering journals and will attend conferences around the country.
