Estimates of wind effects on rigid buildings by database-assisted design (DAD) methods can be far more accurate than those based on information available in standards. An upgraded version of DAD is presented that streamlines the wind engineering/structural

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
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
The present study investigates the characteristics of obscuring media inside an optical smoke cell, which is developed as a bench-scale testing facility for the evaluation of thermal imagers used by fire fighters. The smoke obscuration conditions through

The National Institute of Standards and Technology (NIST) has completed construction of a new facility, the National Fire Research Laboratory (NFRL), which allows scientists and engineers to conduct research on the response of real-scale structural systems
The performance of tile roofing assemblies as well as untreated cedar shake roofing assemblies exposed to continuous firebrand showers were compared. Specifically, experiments were conducted for two types of concrete tile roofing assemblies (flat and
The fire blocking performance of barrier fabrics laminated to upholstery materials was investigated. The results are two-fold. The first involves information gathered directly from cone calorimetry tests conducted on foam/fabric composites to better

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
Research was conducted on the performance of currently available smoke alarms to the new fire and cooking nuisance source tests specified in ANSI/UL 217 Standard for Safety of Smoke Alarms, 8th Edition. The standard calls for additional room-scale fire
A series of fourteen experimental tests on six 9 ft. × 12 ft. (2.7 m × 3.7 m) shear wall specimens consisting of cold-formed steel framing sheathed on one side with light-gauge steel adhered to gypsum board and on the opposite side with plain gypsum board

The contribution of air leakage to heating and cooling loads has been increasing as the thermal resistance of building envelopes continues to improve. Easy-to-access data are needed to convince building owners and contractors that enhancing the
As structures are exposed to wind, stagnation planes are produced around structures. Using full-scale experiments, the authors demonstrated that firebrands may accumulate in these stagnation planes. In a subsequent full-scale study performed by the authors
The 2016 Fort McMurray, Canada, Wildland-Urban Interface (WUI) fire displaced more than 80,000 people, destroyed nearly 2,400 structures, and shut down nearly a quarter of Canada's oil production. Large outdoor fires in Japan mainly occur due to post

A durable and flexible silicone-based backcoating (halogen and formaldehyde free) is applied to the backside of an otherwise smoldering-prone and flammable fabric. When exposed to fire, cyclic siloxanes (produced by thermal decomposition of the backcoating
A series of measurements were made to characterize the global properties of moderate-sized pool fires steadily burning in a quiescent environment. A wide range of parameters were considered including lightly and heavily sooting hydrocarbon fuels (methane
A series of measurements was made to characterize the structure of a moderate-sized methanol pool fire steadily burning in a quiescent environment. Time averaged local measurements of temperature and gas species concentrations were made in a steadily

Upon the request of the Food and Drug Administration (FDA), a comprehensive literature review was conducted to gather and analyze existing research related to airborne emissions from non-smoldering cigarette butts. Based on the results from the literature
This paper explores using blue laser triangulation sensors to measure displacement of a target located behind or in the close proximity of natural gas diffusion flames. This application is relevant for building fire testing. Distortion of the measurement
This Technical Note develops a method for identifying residential fire incidents, reported to the National Fire Incident Reporting System (NFIRS), with missing information regarding the item first ignited (IFI) or item most contributing to flame spread
