INFLUENCE OF MATERIAL MODELS ON PREDICTING THE FIRE BEHAVIOR OF STEEL COLUMNS

February 19, 2016
Author(s)
Lisa Y. Choe, Chao Zhang, William E. Luecke, John L. Gross, Amit Varma
Finite-element (FE) analysis was used to compare the high-temperature responses of steel columns with two different stress–strain models: the Eurocode 3 model and the model proposed by National Institute of Standards and Technology (NIST). The comparisons

Firebrand Production from Building Components Fitted with Siding Treatments

February 1, 2016
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Firebrand production from real-scale building components under well-controlled laboratory conditions was investigated. Re-entrant corner assemblies were ignited and during the combustion process, firebrands were collected to determine the size/mass

Measurement Challenges and Metrology for Monitoring CO2 Emissions from Smokestacks Workshop Summary

January 20, 2016
Author(s)
Aaron N. Johnson, Rodney A. Bryant, Tamae M. Wong, James R. Whetstone, Eric Harman, Woong Kang, Keith A. Gillis, Hsin-Hung Lee, Iosif I. Shinder, Liang Zhang
On April 20-21, 2015, NIST hosted a workshop that, through measurement science, enabled the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG)

FIRE-STRUCTURE INTERACTION EXPERIMENT PLAN FOR FULL-SCALE COMPOSITE FLOOR SYSTEM

January 12, 2016
Author(s)
Lisa Y. Choe, John L. Gross, William L. Grosshandler, Matthew F. Bundy
The newly-constructed National Fire Research Laboratory (NFRL) at the National Institute of Standards and Technology (NIST) provides an opportunity for the structural fire research community to undertake experimental research here-to-for not possible. This

PLANETARY BOUNDARY LAYER MODELING AND TALL BUILDING DESIGN

January 1, 2016
Author(s)
Emil Simiu, Liang Shi, DongHun Yeo
Recent research into Planetary Boundary Layer (PBL) flows accounts for the difference between �neutral� and �conventionally neutral� flows. Of interest in structural engineering are �conventionally neutral� PBL flows, that is, flows affected by transport

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
