Anthony P. Hamins, Nelson P. Bryner, Albert W. Jones, Galen H. Koepke, casey grant, Anand Raghunathan
This report summarizes the results of the Smart Firefighting Workshop held March 24 and 25, 2014, in Arlington, Virginia and sponsored by the National Institute of Standards and Technology (NIST). The Workshop provided a forum to help identify and

Ignition of Mulch Beds Exposed to Continuous-Wind Driven Firebrand Showers

August 3, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Koji Kagiya, Junichi Suzuki, Yoshihiko Hayashi
A series of experiments were conducted to examine ignition of mulch beds to continuous, wind-driven firebrand showers. Shredded hardwood mulch, fitted in beds 1.2 m by 1.2 m with a thickness of 51 mm, was attached to a non-combustible re-entrant corner

The Use of Elevators for Evacuation in Fire Emergencies in International Buildings

July 21, 2014
Author(s)
Max T. Kinateder, Hidemi Omori, Erica D. Kuligowski
The purpose of this report is to provide an overview of elevator evacuation from high-rise buildings with a focus on the safety of mobility impaired occupants. It addresses the specifics of elevator evacuation as well as relevant building codes and its

Quantitative Infrared Imaging of Impinging Turbulent Buoyant Diffusion Flames

July 2, 2014
Author(s)
Randall J. McDermott, Ashish Newale, Brent Rankin, Harshad Lalit, Jay P. Gore
Radiation from buoyant diffusion flames with and without impingement on a flat plate is studied using a unique quantitative comparison of measured and simulated images. The coupling between the stagnation boundary layer and upstream buoyant shear layer

BEHAVIOR OF STEEL COMPONENTS SUBJECTED TO LOCALIZED FIRE

June 11, 2014
Author(s)
Chao Zhang, John L. Gross, Lisa Y. Choe
Recent numerical studies on the behavior of steel components subjected to a localized fire are presented. Sequentially coupled thermo-mechanical simulations were conducted to predict the steel temperature distribution, the deformation mode and failure

USA - Characteristics, Impacts, and Future Directions

June 11, 2014
Author(s)
Sarah Slaughter, Douglas Thomas, Robert E. Chapman
Investments in the built environment provide the basis for civil society and commerce, and construction is an engine of growth for the U.S. economy, equaling approximately 3 % to 5 % of GDP. Current U.S. annual expenditures for construction-related R&D are

Experimental Study of Firebrand Transport

June 1, 2014
Author(s)
Samuel L. Manzello, Kuibin Zhou, Sayaka Suzuki
The NIST Firebrand Generator (NIST Dragon) has been used to quantify the vulnerability of structures to ignition by firebrand attack. The Firebrand Generator is also as useful device to study firebrand transport, and has been used to validate firebrand

Exposing Decking Assemblies to Continuous Wind-Driven Firebrand Showers

June 1, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki
A series of experiments were conducted to examine potential vulnerabilities of wood decks to continuous, wind-driven firebrand showers. Sections of wood decks (1.2 m by 1.2 m) were constructed and attached to a re-entrant corner assembly. The deck

Author(s)
Samuel L. Manzello, Sayaka Suzuki, Junichi Suzuki, Koji Kagiya, Yoshihiko Hayashi
Wildland-Urban Interface (WUI) fires have caused significant destruction to communities throughout the world. WUI fires continue to burn in the USA; most recently in Texas in 2011, Colorado, and California in 2012, and Arizona, Colorado, and California in

Flame Inhibition by CF3CHCl2 (HCFC-123)

May 20, 2014
Author(s)
Valeri I. Babushok, Gregory T. Linteris, Oliver Meier, John Pagliaro
A kinetic model is suggested for hydrocarbon-air flame propagation with addition of hydrochloroflurocarbon (HCFC) fire suppressants, encompassing the combined chemistry of fluorine- and chlorine-containing species. Calculated burning velocities using the

The Case for Delivering the Infrastructure for Digital Building Regulations

May 19, 2014
Author(s)
Mark E. Palmer, James H. Garrett
The building industry uses numerous engineering standards, building codes, specifications and regulations and a diverse set of industry vocabularies to describe, assess, and deliver constructed facilities. As part of the expanding use of building
