Hardening Structures to Resist Wildland-Urban (WUI) Fire Exposures

November 14, 2014
Author(s)
Samuel L. Manzello
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. In the USA, over 46 million homes in 70,000 communities are at risk of WUI fires [1-2]. Historically, fire safety

Hydrocarbon Flame Inhibition by C3H2F3Br (2-BTP)

November 14, 2014
Author(s)
Valeri I. Babushok, Gregory T. Linteris, Donald R. Burgess Jr., Patrick T. Baker
The kinetic mechanism of hydrocarbon flame inhibition by the potential halon replacement 2-BTP has been assembled, and is used to study its effects on premixed methane-air flames. Simulations with varying CH4-air stoichiometry and agent loading have been

Mechanisms of aging and release from weathered nanocomposites

October 31, 2014
Author(s)
Tinh Nguyen, Wendel Wohlleben, Li Piin Sung
Polymer nanocomposites are increasingly used in outdoor structures. However, polymers are susceptible to degradation by solar ultraviolet (UV) radiation, which potentially releases nanofiller during polymer nanocomposites' life cycle. Such release may pose

Carbon Monoxide Exposure from Portable Generators

October 28, 2014
Author(s)
Steven J. Emmerich, Andrew K. Persily, Liangzhu Wang
Serious concerns exist about the hazard of acute residential carbon monoxide (CO) exposures from portable gasoline-powered generators, which can result in death or serious adverse health effects. As of April 23, 2013 and as shown in Figure 1, the U.S

Hardening of Structures to Wildland-Urban Interface (WUI) Fire Expsoures

Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. In the USA, over 46 million homes in 70,000 communities are at risk of WUI fires [1-2]. These fires have destroyed

Sensitivity Analysis of Installation Faults on Heat Pump Performance

October 8, 2014
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
Numerous studies and surveys indicated that typically-installed HVAC equipment operates inefficiently and wastes considerable energy due to different installation errors (faults), e.g., improper refrigerant charge, incorrect airflow, oversized equipment

A Review of Risk Perception in Building Fire Evacuation

October 1, 2014
Author(s)
Max T. Kinateder, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock
Risk perception (RP) is studied in many research disciplines (e.g., safety engineering, psychology, or sociology), and the contexts surrounding the ways in which different concepts of RP are applied vary greatly. Definitions of RP can be broadly divided

Structural Design for Fire: A Survey of Building Codes and Standards

October 1, 2014
Author(s)
Dat Duthinh
This document is a critical assessment of building codes and standards pertaining to structural design for fire from the United States, Canada, European Union members, Japan, New Zealand and Australia. These countries were selected because of their

Universal scaling law for the flow of non-Newtonian colloidal suspension

October 1, 2014
Author(s)
Nicos Martys, William L. George, Maxime Liard, Pascal Hebraud, Didier Lootens
It has been observed that flow curves (viscosity vs shear-rate) of spherical non-colloidal particles suspended in a non-Newtonian fluid matrix can be rescaled so as to collapse onto the flow curve of the matrix fluid. This result is surprising given the

A Review of Risk Perception in Building Fire Evacuation

September 25, 2014
Author(s)
Max Kinateder, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock
Risk perception (RP) is studied in many research disciplines (e.g., safety engineering, psychology, and sociology), and the context in which RP is studied varies greatly. Definitions of RP can be broadly divided into expectancy- value and risk-as-feeling

Movement on Stairs During Building Evacuations

September 25, 2014
Author(s)
Erica D. Kuligowski, Richard Peacock, Paul A. Reneke, Emily A. Wiess, Jason D. Averill, Robert Hagwood, Enrico Ronchi, Bryan Hoskins, Michael Spearpoint
The time that it takes an occupant population to reach safety when descending a stairwell during building evacuations is typically described by measureable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn

Assessing the Verification and Validation of Building Fire Evacuation Models

September 19, 2014
Author(s)
Enrico Ronchi, Erica D. Kuligowski, Daniel Nilsson, Richard Peacock, Paul A. Reneke
To date there is no International standard on the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance, the tests presented within the

White Paper on Fire Behavior of Steel Structures

September 18, 2014
Author(s)
Maria Garlock, Jo? Kruppa, Guo-Qiang Li, Li, Bin Zhao
This white paper presents the state-of-the-art of large-scale experiments, modeling, and performance- based design efforts in fire behavior of steel structures

White Paper on Fire Resistance of Concrete Structures

September 18, 2014
Author(s)
Luke Bisby, Hossein Mostafaei, Pierre Pimienta
This white paper presents the current, international, state-of-the-art large-scale experimental, modeling, and performance-based design (PBD) efforts related to structural fire resistance of concrete structures. The paper addresses these topics with

White Paper on Fire Resistance of Timber Structures

September 18, 2014
Author(s)
Andrew Buchanan, Birgit SP Wood Technology, Sweden tman, Andrea Frangi
Fire resistance of timber structures is a very large field. In order to keep this document relatively small, the scope of is limited as follows: • This report attempts to define a Performance-Based framework for the fire safety design of multi-story timber
