B-roll and computer simulated animations for WTC investigation
B-roll
- Video showing
various aspects of fire tests of truss elements similar to ones in the
WTC towers. (May 7, 2003)
WTC_validation_tests.ram
- Video showing
recovered WTC steel, early WTC computer simulations and microanalysis
of steel. (Aug. 21, 2002)
WTCb-roll_Stop.ram
- Video showing
fire test of mockup WTC office environment with multiple workstations—from
two camera angles (December 2003)
WTC_firetest1.ram
- High-speed video
(30,000 frames per second) of a 4-millimeter-square sample of WTC steel
being impact tested by NIST's Kolsky Bar apparatus to determine the
steel's response to stress similar to the impact of an aircraft. (December
2003)

Animations
- Comparison of
two computer simulations of the fire behavior in the upper stories of
the WTC North Tower (1 WTC) based on different internal conditions and
fuel distribution. The left simulation shows very large flames extending
from the exterior damage holes with the right showing few flames extending
out. The simulation on the right seems to agree more with pictorial
records:

- Simulation of
the WTC South Tower (2 WTC) fireball seconds after impact of the plane:
WTCanimation2.ram
- A computer simulation
showing the smoke plume generated by the fire in the WTC North Tower
(1 WTC).
WTCanimation3.ram
- A computer simulation
showing the combining of the smoke plumes generated from the fires in
the upper stories of WTC North and South Towers (1 WTC and 2 WTC):
WTCanimation4.ram
- Computer simulation
showing the impact of a Boeing 767 aircraft engine into an exterior
wall panel and two core columns of a WTC tower.
WTC_engine1.ram
- Computer simulation
showing the impact of a Boeing 767 aircraft engine into an exterior
wall panel, floor system and core columns of a WTC tower.
WTC_engine2.ram
- Computer simulation
(containing 90,000 elements) showing the response of the WTC North Tower
to wind loads.
WTC_windloads.ram
- Computer simulation
showing some of the progression of the fires on the 97th floor of the
WTC North Tower.
WTC_fireon97th.ram
- Computer simulation
(containing 40,000 elements) showing the response of the 96th floor
of the WTC North Tower to gravity loads.
WTC_gavityloads.ram
- Computer simulation
showing the response to gravity and elevated temperatures of a strip
of floor (including floor trusses and concrete slab) connected to an
exterior column of a WTC tower.
