Technique for Extrapolating Absorption Coefficient Measurements to High Temperatures

December 1, 2005
Author(s)
Kaoru Wakatsuki, Stephen P. Fuss, Anthony Hamins, Marc R. Nyden
An extrapolation technique that provides semi-quantitative estimates for the infrared absorption coefficients of gaseous fuels at temperatures beyond those for which measurements are generally practical (>700 K) is presented. The new method is based on a

Visual Evidence, Damage Estimates, and Timeline Analysis (Appendices D-G) Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5A)

December 1, 2005
Author(s)
William M. Pitts, Kathryn M. Butler, Valentine Junker
This report summarizes the collection and analysis of visual material used for the National Institute of Standards and Technology (NIST) World Trade Center (WTC) Investigation. The task consisted of four major subtasks: 1) identification, collection, data

What a User Should Know When Selecting an Evacuation Model.

December 1, 2005
Author(s)
Erica D. Kuligowski, Steve M. Gwynne
In recent years, evacuation models have been increasingly applied in an attempt to understand the outcome of emergency egress scenarios. This has been due to the increased use of performance-based design and the availability of cost-effective, high

Ignition of Vegetation and Mulch by Firebrands in Wildland/Urban Interface (WUI) Fires.

November 13, 2005
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
Firebrands or embers are produced as trees and structures burn in wildland/urban interface (WUI) fires. Hot firebrands ultimately come to rest and may ignite fuels far removed from the fire, resulting in fire spread. It is believed that firebrand showers

Use of Visual Imagery for the NIST World Trade Center Investigation

November 13, 2005
Author(s)
William M. Pitts, Kathryn M. Butler, Valentine Junker
The attack on the World Trade Center (WTC) in New York City on September 11, 2001 by terrorists flying hijacked commercial aircraft into the two towers (WTC 1 and WTC 2) was among the worst building disasters in the history of the United States. In

Rheology Measurement of Fresh concrete With a Mixing Truck

November 2, 2005
Author(s)
S Amziane, Chiara C. Ferraris, E Koehler
The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with

Characterization of Candle Flames

November 1, 2005
Author(s)
Anthony P. Hamins, Matthew F. Bundy, Scott E. Dillon
Common household open flame and radiant ignition sources are the actual or suspected cause for many fires. The purpose of this research is to identify the burning behavior and properties of common candles in order to provide additional tools for use by
