Fire Structure Interface for the World Trade Center Towers

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
The collapse of the World Trade Center towers on September 11, 2001, resulting from a combination of aircraft impact damage and subsequent fires, was studied as part of the Federal Building and Fire Safety Investigation of the World Trade Center Disaster

Localized Ignition and Subsequent Flame Spread Over Solid Fuels in Microgravity

February 19, 2017
Author(s)
Takashi Kashiwagi, Y N. Nakamura, Kuldeep Prasad, Howard R. Baum, S L. Olson, O -. Fujita, K K. Nishizawa, K. Ito
Ignition and subsequent flame spread over a paper sample and a PMMA sheet in microgravity are studied experimentally and theoretically. New results obtained during last two years are described.

Real Fire Performance of Partition Assemblies: Insulated and Non-Insulated Assemblies

February 19, 2017
Author(s)
Samuel Manzello, Richard Gann, S R. Kukuck, Kuldeep Prasad, Walter W. Jones
Two gypsum wall assemblies were exposed to intense real-scale compartment fires, from the time of ignition to beyond flashover. The construction of each assembly (2.44 m by 2.44 m) was identical, with the exception that one of the wall assemblies was

Simulating Fire Dynamics and Thermal Response of Structural Elements

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
Simulation of the effects of severe fires on the structural integrity of builings requires a close coupling between the gas phase energy release andtransport phenomena and the stress analysis in the load bearing materials. The connection between the two is

Structural Analysis of a High-Rise Composite Frame Exposed to Fire

February 19, 2017
Author(s)
Dat Duthinh, Kuldeep Prasad
This paper presents a simplified, planar analysis of World Trade Center Tower 1 (WTC1), starting from a computer simulation of the fire using computational fluid dynamics, and progressing through a thermal and a structural analysis of the damaged structure

Greenhouse Gas Emissions and Dispersion 3. Reducing Uncertainty in Estimating Source Strength and Location through Plume Inversion Models

September 30, 2015
Author(s)
Kuldeep R. Prasad, Adam L. Pintar, Heming Hu, Israel Lopez Coto, Dennis T. Ngo, James R. Whetstone
Recent development of accurate instruments for measuring greenhouse gas concentrations and the ability to mount them in ground based vehicles has provided an opportunity to make temporally and spatially resolved measurements in the vicinity of suspected
