“S. Shyam Sunder is the Deputy Director of the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST), and he also serves as the lead investigator for the federal building and fire safety investigation of the World Trade Center (WTC) disaster.

In this brief interview, Dr. Sunder explains the methodologies NIST used in its analysis of the WTC disaster, and he offers recommendations for improving building performance, occupant evacuation and emergency response.

How did NIST determine which methodologies to use in its analysis of the World Trade Center (WTC) disaster?

Since the collapse of the two towers did not leave behind much physical evidence, we used the following methodologies in our analysis:

1. We determined the properties of the steel recovered from the collapsed buildings to analyze the performance of the building components during the aircraft impact and subsequent fires.

2. We reviewed video footage and photographs of the attacks and collapse to determine the condition of the buildings following aircraft impact, the evolution of the fires and the subsequent deterioration of the structures.

3. We established a baseline performance analysis of the WTC towers to estimate the expected performance of the towers under normal design loads and conditions and the capacity of the towers to withstand the attacks of September 11, 2001.

4. We conducted four-step simulations of the behavior of each tower on September 11, 2001. The four steps included:

1. The aircrafts’ impact into the towers, the resulting distribution of aircraft fuel and the damage to the structures, partitions, thermal insulation materials and building contents.
2. The evolution of multi-floor fires.
3. The fires’ heating and weakening of structural elements.
4. The response of the damaged and heated building structures and the progression of structural component failures, which lead to the initiation of the collapse of the towers.

To increase the accuracy of the simulation results, NIST used:

1. Visual evidence.
2. Eyewitness accounts from both inside and outside the buildings.
3. Laboratory tests involving large fires and the heating of structural components.
4. Formal statistical methods to identify influential parameters and to quantify variability in the analysis results.”

Dr. S. Shyam Sunder, (head of NIST)

A quote from a Mark Jacobson New York Magazine article (March 21, 2006) entitled “The Ground Zero Grassy Knoll” “I asked Dr. Sunder about 7 WTC. Why was the fate of the building barely mentioned in the final report? This was a matter of staffing and budget, Sunder said. He hoped to release something on 7 WTC by the end of the year. NIST did have some “preliminary hypotheses” on 7 WTC, Dr. Sunder said. “We are studying the horizontal movement east to west, internal to the structure, on the fifth to seventh floors.” Then Dr. Sunder paused. “But truthfully, I don’t really know. We’ve had trouble getting a handle on building No. 7.” [read more]

SHYAM SUNDER QUOTES

“You really have a new kind of progressive collapse that they discovered here . . .fire induced progressive collapse.” Shyam Sunder

“The collapse of WTC 7 was primarily due to fires.” – Shyam Sunder

“NIST used detailed data…… to create the most complex computer simulation ever made.” ~ Shyam Sunder

“The measurements have indicated that Tower one collapsed in about 11 seconds and Tower two collapsed in about 9 seconds…..this is essentially the rate at which free fall would happen.” – Shyam Sunder NIST

“Another theory involved a hypothetical blast event. Our analysis calculated that the minimum charge needed to make the critical column fail would have produced a huge 130-decibel sound, audible over half a mile away. None of the videos or witness reports provided any evidence of this.” – Shyam Sunder

“We knew from the beginning of our study that understanding what happened to Building 7 on 9/11 would be difficiult. IT DID NOT FIT ANY TEXTBOOK DESCRIPTION THAT YOU COULD READILY POINT TO AND SAY, YES THAT’S WHY THE BUILDING FAILED.” Dr, Shyam Sunder, degree in engineering at MIT

Dr. Shyam Sunder, of the National Institutes of Standards and Technology (NIST), which investigated the collapse of WTC 7, is quoted in Popular Mechanics (9/11: Debunking the Myths, March, 2005) as saying: “There was no firefighting in WTC 7.”

New Evidence Is Reported That Floors Failed on 9/11
http://www.nytimes.com/2003/12/03/nyregion/new-evidence-is-reported-that-floors-failed-on-9-11.html?

“The investigators, who are carrying out a two-year, $16 million analysis of the collapses, made it clear that they had not yet settled on a final explanation. They said, though, that their findings gave new weight to a theory that the failure of the floors weakened the towers’ internal structure to the point that the entire buildings came down.”

“According to an alternative theory of the collapse, the planes that smashed into the towers damaged the towers’ vertical structural columns so severely that the buildings were virtually certain to fall. In that view, none of the buildings’ many structural novelties — the towers were daring engineering innovations in their day — would have played a significant role in the collapses.”

“Finally, an unexplained cascade of molten metal from the northeast corner of the south tower just before it collapsed might have started when a floor carrying pieces of one of the jetliners began to sag and fail. The metal was probably molten aluminum from the plane and could have come through the top of an 80th floor window as the floor above gave way, Dr. Pitts said.”

“The studies of the floor trusses and the design of the towers are just two elements of the investigation, which is carrying out computer calculations of the collapses, rebuilding pieces of the towers in order to test them in real fires, and piecing together a highly detailed chronology of the response to the attack.”

“Whether the fuel was taken into account or not is an open question,” Dr. Sunder said. It is also unclear, he said, ”whether the extent of the loss of human life as a result of that” was taken into account.”
