The Process of Human Behavior in Fires

May 15, 2009
Author(s)
Erica D. Kuligowski
Evacuation models, including engineering hand calculations and computational tools, are used to evaluate the level of safety provided by buildings during evacuation. However, there is a lack of available data and theory on occupant behavior for use by

The Origin of Critical Relative Humidity in Adhesion

May 11, 2009
Author(s)
Christopher C. White, Kar T. Tan, Bryan D. Vogt, Donald L. Hunston
Water is ubiquitous in the atmosphere. Unfortunately, adhesive bonding is susceptible to the environmental attack of water leading to significant depreciation in joint strength and subsequently to premature failures [1-6]. This susceptibility of bonding to

Calculation of Relative Thermal Elongation of Structural Steels

May 2, 2009
Author(s)
Dilip K. Banerjee, Ursula R. Kattner
In the recent past, there has been a number of studies toward predicting the thermal and structural behavior of components subjected to elevated temperature due to an exposure to fire. Numerical modeling has been applied quite extensively toward this end

Economic Analysis of Egress and Life Safety Costs

April 27, 2009
Author(s)
Robert E. Chapman, Allison L. Huang, David T. Butry
In 2007, the latest year for which construction data are available, the value of construction put in place was $1.1 trillion. Statistics on the total cost of fire in the U.S. are published by the National Fire Protection Association (NFPA). Of particular

Extending the Mixture Fraction Concept to Address Under-Ventilated Fires

April 6, 2009
Author(s)
Kevin B. McGrattan, Jason E. Floyd
A common technique in computational fluid dynamics (CFD) modeling of fire is to assume single step, infinitely fast combustion, in which case the transport equations of all gas species can be combined into one for a single conserved scalar called the

Fire-Front Propagation Using the Level Set Method

April 1, 2009
Author(s)
Ronald G. Rehm, Randall J. McDermott
Propagation of an outdoor fire front in wildland or in a combination of wildland and structural fuels (the so-called wildland-urban interface or WUI fire), can be modeled as an initial-value problem using either a Lagrangian or an Eulerian description. The

A History of Fire Testing: Past, Present, and Future.

March 30, 2009
Author(s)
James R. Lawson
This paper discusses the breakthroughs in science and engineering that have brought fire testing technology to its current state of maturity and provides insight into the possibilities for future fire test development by highlighting some areas where

Mass Notification Messages: Workshop Proceedings

March 30, 2009
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Jason D. Averill, Richard W. Bukowski
This workshop provided a forum to discuss research and best practices regarding mass notification message creation and dissemination. The goal of the workshop was to provide a forum where representatives from federal agencies could exchange ideas and

FIREBRAND ATTACK ON CERAMIC TILE ROOFING ASSEMBLIES

March 17, 2009
Author(s)
Samuel L. Manzello, Yoshihiko Hayashi, Takefumi Yoneki, Yu Yamamoto
The present study is concerned with investigating the ignition of ceramic roofing assembles (Spanish tile roofing) to a controlled firebrand attack using the Firebrand Generator. Current standards exist to test ignition of roofing decks to firebrands by

Evaluation of Image Quality of Thermal Imagers used by the Fire Service

February 27, 2009
Author(s)
Francine K. Amon, Andrew J. Lock
This document reports on the test results of an evaluation of the image quality of thermal imaging cameras used by the fire service. The test methods used were consistent with the image quality test methods included in Draft National Fire Protection
