Helium Dispersion in an Attached Single-Car Residential Garage with and Without Vehicle

October 2, 2012
Author(s)
William M. Pitts, Jiann C. Yang, Marco G. Fernandez, Kuldeep R. Prasad
The dispersion and loss of helium inside a single-car residential garage attached to a single-family house was experimentally characterized by recording time-resolved helium concentrations at multiple locations in the garage and at a single location in the

High Pressure Release and Dispersion of Hydrogen in a Partially Enclosed Compartment

March 1, 2011
Author(s)
Kuldeep R. Prasad, Thomas G. Cleary, William M. Pitts, Jiann C. Yang
The study of compressed hydrogen release from high-pressure storage systems has practical application for hydrogen and fuel cell technologies. Such releases may occur either due to accidental damage to a storage tank or connecting piping, or direct PRD

A Materials Science-Based Approach to Characterizing Fire Resistive Materials

April 9, 2009
Author(s)
Dale P. Bentz, Christopher C. White, Kuldeep R. Prasad, Daniel R. Flynn, Donald L. Hunston, Kar T. Tan
While ASTM E119-07a is commonly employed to establish a fire rating for a fire resistive material (FRM)/steel assembly, the test method provides little quantitative information on either the thermophysical or adhesion properties of the FRM, beyond

NUMERICAL SIMULATION OF FIRE SPREAD ON POLYURETHANE FOAM SLABS

March 17, 2009
Author(s)
Kuldeep R. Prasad, Roland Kramer, Nathan D. Marsh, Marc R. Nyden, Thomas J. Ohlemiller, William M. Pitts, Mauro Zammarano
The NIST Fire Dynamics Simulator (FDS) is used extensively by the fire protection engineer for performance based design and forensic analysis. The equations of motion describing the gas phase are relatively well known and the approximations in the various

Fire Induced Thermal and Structural Response of the World Trade Center Towers

September 26, 2008
Author(s)
Kuldeep R. Prasad, Anthony P. Hamins, Therese P. McAllister, John L. Gross
Over the past several years, there has been a resurgence of interest in studying the response of building structures to fires. Typically, the thermal loading for structural analysis of a building subject to fire is obtained from a standard time-temperature

Structural Fire Response and Probable Collapse Sequence of World Trade Center Building 7 (Volume 1). Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-9) ***DRAFT for Public Comments***

August 1, 2008
Author(s)
Therese P. McAllister, Richard G. Gann, Jason D. Averill, John L. Gross, William L. Grosshandler, James R. Lawson, Kevin B. McGrattan, William M. Pitts, Kuldeep R. Prasad, Fahim Sadek, Harold E. Nelson
This is the primary technical report on the National Institute of Standards and Technology (NIST) investigation of the collapse of World Trade Center Building 7 (WTC 7), conducted under the National Construction Safety Team Act. The investigation

Experiments and Modeling of Unprotected Structural Steel Elements Exposed to a Fire

September 18, 2005
Author(s)
Anthony P. Hamins, Kevin B. McGrattan, Kuldeep R. Prasad, Alexander Maranghides, Therese P. McAllister
A large-scale fire experiment was conducted to assess the accuracy of a combination of gas and solid-phase models designed to predict the temperatures of structural steel elements exposed to a fire. The experiment involved a 2 MW heptane spray fire in a
