Wildland-Urban Interface Fires: Overview and Research Needs

February 19, 2017
Author(s)
William E. Mell, Samuel Manzello, Alexander Maranghides, Ronald G. Rehm
Wildfires that spread into wildland-urban interface (WUI) communities present a significant challenge on a number of fronts. In the United States the WUI accounts for a significant portion of wildfire suppression and risk mitigation costs. Research on fire

Wind and Seismic Effects - Proceedings of the 38th Joint Panel Meeting

February 19, 2017
Author(s)
Stephen A. Cauffman
This publication is the Proceedings of the 38th Joint Meeting of the U.S.-Japan Panel on Wind and Seismic Effects. The meeting was held at the National Institute of Standards and Technology, Gaithersburg, Maryland during 15-17 May 2006. The Proceedings

Wind Effects on Tall Buildings: A Database-Assisted Design Approach

February 19, 2017
Author(s)
William P. Fritz, Emil Simiu
A rigorous procedure that calculates wind-induced effects on tall buildings is presented. The method, an extension of Database-Assisted Design (DAD), uses sets of time histories of pressures recorded simultaneously in the wind tunnel at a large number of

Wind Load Factors for Tall Building Design and the ASCE 7 Standard

February 19, 2017
Author(s)
Rene D. Gabbai, Emil Simiu
Wind load factors incorporated in the ASCE 7 Standard are based on rough approximations of wind effects and the uncertainties inherent in them. These factors are routinely applied to tall building design, even though the original calculations on which they

Wind Speeds for the Estimation of World Trade Center Towers' Response

February 19, 2017
Author(s)
William P. Fritz, Fahim H. Sadek, Emil Simiu
Estimates of the World Trade Center (WTC) towers response to wind by two North American wind engineering laboratories differed from each other by almost 40 %. A recent investigation by the National Institute of Standards and Technology determined that

Wind Effects on Flame Spread and Ember Spotting Near a Structure

February 6, 2017
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Glenn P. Forney, Eric Auth
In wildland-urban interface (WUI) fires, combustible materials pose a potential threat to contiguous or nearby structures. Flame spread and firebrand spotting have been studied in a series of field experiments involving fences and mulch beds under a

Generating Wind-Driven Firebrand Showers Characteristic of Burning Structures

February 1, 2017
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Firebrands are a significant source leading to structures ignited and lost in large outdoor fires, such as Wildland–Urban Interface (WUI) fires, a large international problem, and urban fires, common in Japan. Sadly, hardly any information is available

Impact of UV irradiation on multiwall carbon nanotubes in nanocomposites: formation of entangled surface layer and mechanisms of release resistance

January 31, 2017
Author(s)
Tinh Nguyen, Elijah J. Petersen, Bastien T. Pellegrin, Justin M. Gorham, Thomas F. Lam, Minhua Zhao, Li Piin Sung
Carbon nanotubes (CNTs) are increasingly used in consumer and structural polymeric products to enhance a variety of properties. Under weathering, the polymer matrix will degrade and the nanofillers will potentially be released from the products, which

2015 Location-Based Services R&D Summit Report

January 30, 2017
Author(s)
Harris Feldman, Adam H. Danielson
The Public Safety Communications Research Program (PSCR) convened over 80 stakeholders at the National Institute of Standards and Technology (NIST) Boulder, CO campus to build on the findings presented in the 2015 Location-Based Services (LBS) Summit- held

Performance of Metal and Polymeric O Ring Seals during Beyond-Design-Basis Thermal Conditions

December 28, 2016
Author(s)
Jiann C. Yang, Edward J. Hnetkovsky, Doris L. Rinehart, Marco G. Fernandez, Felix Gonzalez, Joseph Borowsky
This paper summarizes the small scale thermal exposure test results of the performance of metallic and polymeric O- ring seals typically used in radioactive material transportation packages. Five different O-ring materials were evaluated: Inconel/silver
