Comparative study of methods to measure the density of Cementitious powders

December 14, 2015
Author(s)
Michelle A. Helsel, Chiara F. Ferraris, Dale P. Bentz
The accurate measurement of the density of hydraulic cement plays an essential role in the determination of concrete mixture proportions. As more supplementary cementitious materials (SCM), such as fly ash and slag, or cement replacement materials, such as

Energy Use Consequences of Ventilating a Net-Zero Energy House

December 2, 2015
Author(s)
Lisa C. Ng, William V. Payne
A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland to demonstrate that a home similar in size, aesthetics, and amenities to those in the

Characterizing the thermal effects of High Energy Arc Faults

November 30, 2015
Author(s)
Anthony D. Putorti Jr., Nicholas Melly, Scott Bareham, Joseph E. Praydis
International and domestic operating experience involving High Energy Arc Faults (HEAF) in Nuclear Power Plant (NPP) electrical power systems have demonstrated the potential to cause extensive damage to electrical components and distribution systems along

Reduced-scale Experimental Facility to Characterize Firebrand Ignition

November 16, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Large outdoor fires are a problem in Japan and the USA. In order to prevent losing structures to large outdoor fires, it is important to understand the vulnerabilities of structures to firebrand showers and then, strengthen structures to these exposures

A dimensional analysis on firebrand penetration through a mesh screen

November 15, 2015
Author(s)
Jiann C. Yang, Samuel L. Manzello
A dimensional analysis on firebrand penetration through a mesh screen was carried out to provide a framework to correlate a limited set of experimental data previously reported by Manzello et al. (2011). Two dimensionless variables were obtained. The

A Case Study of a Community Affected by the Waldo Fire Event Timeline and Defensive Actions

November 9, 2015
Author(s)
Alexander Maranghides, Derek McNamara, Robert Vihnanek, Joseph Restaino, Carrie Leland
The National Institute of Standards and Technology (NIST) has a suite of research projects addressing risk reduction in Wildland Urban Interface (WUI) communities. This case study is focused on the Mountain Shadows Community (MSC) in Colorado Springs

Computer Evacuation Models for Buildings

November 9, 2015
Author(s)
Erica D. Kuligowski
N/A for SFPE Handbook Chapters. Included here is text from the chapter introduction: "With the rapid increase in computer capability and the increase in egress model development, there is a need for guidance on evacuation modeling, specifically the process

Heat transfer principles in thermal calculation of structures in fire

November 1, 2015
Author(s)
Chao Zhang, Usmani Asif
Structural fire engineering (SFE) is a relatively new interdisciplinary subject, which requires a comprehensive knowledge of heat transfer, fire dynamics and structural analysis. It is predominantly the community of structural engineers who currently carry

Chemical Kinetics and Fire

October 7, 2015
Author(s)
Gregory T. Linteris, John Griffiths
The purpose of this chapter is to set out the principles of chemical kinetics as they apply to combustion in flames and fires. Chemical equilibrium, which was discussed in a previous chapter, deals with the final preferred state of a given set of reactants

Enforcing realizability in explicit multi-component species transport

October 5, 2015
Author(s)
Randall J. McDermott, Kevin B. McGrattan, Jason Floyd
A strategy is proposed to guarantee realizability of species mass fractions in explicit time integration of the partial differential equations governing fire dynamics, which is multi-component transport problem. For a mixture of $n$ species, the

Assessment of Water Vapor Diffusion in Firefighter’s Protective Clothing

October 1, 2015
Author(s)
Shonali Nazare, Christopher W. Meyer, Daniel M. Madrzykowski
Structural firefighters often encounter hot and humid environments during interior firefighting. The water vapor transfer to and from the skin has great influence on thermo-physiological comfort of the firefigher. Quantitative information on water vapor

Fire Evacuation of People with Mobility Impairments Using Elevators

September 28, 2015
Author(s)
Kathryn M. Butler, Susanne M. Furman, Erica D. Kuligowski
The Final Report on the collapse of the World Trade Center (WTC) Towers recommended that tall buildings be designed for timely full-building evacuations from both building-specific and large-scale events. Since the WTC study, several project efforts have
