Fire Research: Providing New Tools for Fire Investigation

July 1, 2002
Author(s)
Daniel M. Madrzykowski
Researchers at the National Institute of Standards and Technology's (NIST) Building and Fire Laboratory (BFRL) are working with the U.S. Fire Administration (USFA); the Bureau of Alcohol, Tobacco and Firearms (ATF); and the U.S. Department of Justice to

Global Response Modification Factors vs. Member Ductility-Based Modifiers

July 1, 2002
Author(s)
S K. Kunnath, Hai S. Lew, D Friis
Most building structures today are designed using the response modification factors (R-factors) given in the code for different types of structural systems. This paper examines whether ductility-based modifiers for structural members (m-factors)

Meteorological Extremes

July 1, 2002
Author(s)
Emil Simiu
This entry discusses briefly basic principles of extreme value (EV) estimation (see Extreme value analysis), the role of simulations for the development of relevant meteorological data sets, the interaction between the practical application of the

Modeling Moisture in Residential Buildings with a Multizone IAQ Program

July 1, 2002
Author(s)
Steven J. Emmerich, Andrew K. Persily, Steven J. Nabinger
Multizone airflow and contaminant transport modeling is a valuable tool for researchers and others studying indoor air quality (IAQ) problems in buildings. Although water vapor is not typically thought of as an indoor contaminant, multizone IAQ modeling

NDE of Concrete Structures Strengthened with FRP Using Infrared Thermography

July 1, 2002
Author(s)
M A. Starnes, Nicholas J. Carino, E A. Kausel
Numerical and experimental methods are used to investigate the effectiveness of infrared thermography to estimate the width of subsurface flaws in fiber-reinforce polymer (FRP) laminates bonded to concrete. The study focuses on establishing the potential

Gas-Phase Mechanisms of Fire Retardants

June 28, 2002
Author(s)
Gregory T. Linteris
Fire retardants are added to polymers to increase their ignition time and reduce their heat release rates when burning. They are often described as acting either in the condensed-phase or in the gas-phase, with an understanding that often, both modes can

Data-Assisted Design for Wind Loading

June 1, 2002
Author(s)
Emil Simiu, Fahim Sadek, T Whalen, S Jang, L L. Lu, S M. Diniz, A Grazini, Michael A. Riley
Current ASCE Standard provisions on wind loads for low-rise building design are based on wind tunnel tests conducted at the University of Western Ontario in the 1970's. In spite of the advances they entailed at the time, those provisions are inadequate

Discharge of CF3I in a Cold Simulated Aircraft Engine Nacelle (NIST SP 984)

June 1, 2002
Author(s)
Jiann C. Yang, Samuel L. Manzello, Marc R. Nyden, M D. Connaghan
An aircraft engine nacelle refers to the region between the engine body and its casing. Fuel and hydraulic lines, pumps, and lubrication systems are located within the nacelle. Air is vented through the nacelle to prevent any build-up of combustible vapors

Fragility Curves, Damage Matrices, and Wind-Induced Loss Estimation

June 1, 2002
Author(s)
James J. Filliben, K Gurley, J P. Pinelli, Emil Simiu, M Subramanian
This note presents a conceptual framework for the definition of basic damage states and of the corresponding fragility curves and conditional probabilities, and its use for the estimation of damage matrices. The framework is designed with two

High-Strength Concrete at High Temperature - An Overview

June 1, 2002
Author(s)
Long T. Phan
This paper presents results of NIST's experimental program on the effects of elevated temperature exposure on the mechanical properties and potential for explosive spalling of high strength concrete (HSC). Mechanical properties of HSC were measured by

Measured Versus Predicted Performance of Building Integrated Photovoltaics

June 1, 2002
Author(s)
Mark W. Davis, Arthur H. Fanney, Brian P. Dougherty
The lack of predictive performance tools creates a barrier to the widespread use of building integrated photovoltaic panels. The National Institute of Standards and Technology has created a building integrated photovoltaic (BIPV) test bed to capture

Multizone Modeling Approaches to Contaminant-Based Design

June 1, 2002
Author(s)
A L. Musser, Andrew K. Persily
Indoor air quality is currently addressed in the design process primarily through prescriptive building codes based on specified flow rates. However, a contaminant-based design approach opens the door to design innovation, offering opportunities for

Proceedings of the 12th Halon Options Technical Working Conference

June 1, 2002
Author(s)
Richard G. Gann
This proceedings contains the papers from the 12th Halon Options Technical Working Conference. The topics covered include: results from the DoD Next Generation Fire Suppression Technology Program, total flood applications, passive fire protection

Structural Reliability Estimates and Database-Assisted Design for Wind

June 1, 2002
Author(s)
F Minciarelli, Fahim H. Sadek, Emil Simiu, Mircea Grigoriu
We propose a probabilistic methodology for developing improved estimates of extreme wind effects and load factors in standard provisions for wind loads. We obtained the following results: (1) the discrepancy between current estimates of safety indices for

The Revision of Standard 62: What a Difference a Decade Makes

June 1, 2002
Author(s)
Andrew K. Persily
The American Society of heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has been revising Standard 62,Ventilation for Acceptable Indoor Air Quality since 1991. The two primary motivations for this revision have been 1) to convert the

Home Smoke Alarm Tests, Test Series 2, Report of Test 4017

May 10, 2002
Author(s)
Jason D. Averill, Richard D. Peacock, Richard W. Bukowski, Paul A. Reneke
This Report of Test documents the second series of full scale tests conducted as part of research into the performance of smoke alarms. The first series of tests, conducted in a manufactured home, consisted of fifteen experiments with instrumentation
