In designing a building that will perform reliably over a specified time, a designer needs a vast amount of information about the performance of the available materials and components (hereafter referred to, collectively, as maerials) in the likely service
This document specifies the ISO 10303 application protocol (AP) Edition 2 for the exchange of spatial configuration information of process plants, plant systems and ship systems. This includes shape characteristics, spatial arrangement characteristics, and

The performance of polyurethane (PU) composites reinforced by isocyanate-functionalized multi-walled carbon nanotubes (NCO-fMWCNT) and isocyanate-functionalized carbon nanofibers (NCO-fCNF) has been investigated. NCO-fCNTs and NCO-fCNF were prepared using
A successful simulation of compartment fires using computational fluid dynamics (CFD) must be able to adequately model three significant phenomena: the combustion of fuel, the mixing caused by the buoyancy of hot gasses, and the removal of heat from the

As a result of the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer and the 1990 U.S. Clean Air Act, there began a movement toward phaseout of the use of the halon fire suppressants. The HOTWC was initiated as a forum for such contributory
A recently developed capability allows the routine creation, from National Weather Service Automated Surface Observing System (ASOS) records, of separate sets of extreme non-thunderstorm and thunderstorm wind speeds. Using such records it is possible to
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the American Institute of Steel Construction, sponsored a workshop on automated steel construction on June 6-7, 2002, at the NIST
This document provides an overview of a new ISO standard, ISO/CD 10303-231, for exchanging process engineering information among process design and process simulation software tools and presents three views of this standard. First, it attempts to forecast
complishments and current standards development activities of the American Society for Testing and Materials (ASTM) Subcommittee E06.23, Lead Hazards Associated with Buildings, are summarized. Since the inception, the subcommittee has developed 24
The events of September 11 have generated renewed interest in the use of protected elevators for egress and access. U.S. building codes contain requirements for accessible elevators for assisted evacuation of people with disabilities. Firefighter lifts
A dual burner apparatus has been developed for the purpose of assessing the flammability of a mattress/foundation combination in a manner that correlates with its real world fire behavior. This document sets out the detailed procedure for employing this
This paper presents a critical analysis of the economic impacts of past, ongoing, and planned collaborative research for developing and deploying cybernetic building systems (CBSs) in office buildings. NIST is participating in a public-private partnership
Field inspection (including sampling) and laboratory testing of concrete and concrete-making materials are key activities ensuring that constructed facilities are durable and long lasting. Standards which promote the quality of testing are prepared by ASTM

Two gypsum wall assemblies were exposed to intense real-scale compartment fires, from the time of ignition to beyond flashover. The construction of each assembly (2.44 m by 2.44 m) was identical, with the exception that one of the wall assemblies was

This paper identifies building and building related information that would be useful to first responders (fire, police, EMS) and discusses examples of how the information might be displayed based on a first responder workshop held at NIST in May 2004. The
The National Institute of Standards and Technology (NIST) led reconnaissance to assess the performance of physical structures during Hurricane Katrina and Hurricane Rita. This paper summarizes 1) the major findings of the NIST-led reconnaissance team, 2)
To control the Newton-Raphson solution of a nonlinear algebraic system, a descent method forces each step to reduce some norm of the residual errors. This prevents divergence, but risks stagnation in flat regions of the norm. Employing a family of cost

Six PMMA/SWNT(0.5 wt%) nanocomposite samples intended to have different dispersion levels were prepared by the coagulation method using six different concentrations of SWNTs in DMF from 0.05 mg/ml to 1.2 mg/ml. The morphology of the samples was determined
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the Fully Integrated and Automated Technology (FIATECH) consortium, sponsored a workshop on data exchange standards at the construction job
A series of tragic events in the United States over the past decade, punctuated by the collapse of the World Trade Center on September 11, 2001, has exposed the vulnerability of public buildings to uncontrolled fires, explosions, and biological attack
This report describes the results of a brain storming session conducted by the National Institute of Standards and Technology s Building and Fire Research Laboratory. The session was held as part of the Fourth International Workshop Structures in Fire (SiF
The tests reported herein were intended to gain information on how manufactured home shear walls perform under extreme loads. The specimens tested represent sections from a typical manufactured home. The test results will be used for analytical modeling
Traditional air-handling unit (AHU) control systems link the position of the exhaust air damper, recirculation air damper, and outdoor air damper. Laboratory and field tests on variable-air-volume (VAV) AHU's that use a volume matching to control the
