The time that it takes an occupant population to reach safety when descending a stair during building evacuations is typically estimated by measureable engineering variables such as stair geometry, speed, stair density, and pre-observation delay. In turn

Performance-based methodologies to evaluate the fire performance of structures are needed to move beyond the prescriptive procedures presently in use, which cannot be used to determine actual structural performance in fire. Analytical methods are needed
One of the key concepts of a modernized smart grid is to combine modern communication technology with an improved electric grid to enable energy consumers to exchange information with energy suppliers in order to collaboratively manage electricity supply
A new framework for a risk-informed performance-based approach to fire safety analysis and design has been proposed. It is structured around a paradigm in which the performance analysis is conducted relative to the performance of a building-occupant system
Performance-based methodologies to evaluate the fire performance of structures are needed to move beyond the prescriptive procedures presently in use. Analytical methods are needed for simulating the performance of structural systems, including connections

This study investigates the performance issues associated with the use of handheld portable radios by fire fighters working in elevated temperature environments. Radios may be vulnerable to elevated temperatures that can be encountered during fire fighting
This document is a critical assessment of building codes and standards pertaining to structural design for fire from the United States, Canada, European Union members, Japan, New Zealand and Australia. These countries were selected because of their

This white paper presents the state-of-the-art of large-scale experiments, modeling, and performance- based design efforts in fire behavior of steel structures
This white paper presents the current, international, state-of-the-art large-scale experimental, modeling, and performance-based design (PBD) efforts related to structural fire resistance of concrete structures. The paper addresses these topics with

The purpose of this report is to provide an overview of elevator evacuation from high-rise buildings with a focus on the safety of mobility impaired occupants. It addresses the specifics of elevator evacuation as well as relevant building codes and its
Full-scale fire experiments were conducted at the National Institute of Standards and Technology (NIST) to investigate tire fire interactions with the passenger compartment of a motorcoach. A burner was designed to imitate the frictional heating of hub and

The burden of fire on the U.S. economy continues to be large, comprising approximately $280 billion annually, or 2 percent of GDP. Over the last 30 years, civilian fire deaths and injuries have decreased due to the efforts of many people and organizations

NIST was invited to comment on the articles written for a special issue of the CTBUH Journal, marking the ten years passed since the 2001 9/11 attacks on the World Trade Center. This letter to the editor reacts to the role of the NIST WTC Investigation
The National Electrical Manufacturer's Association (NEMA) and the American Society of Heating Refrigerating, and Air-Conditioning Engineers (ASHRAE) are working to cooperatively develop a national Facility Smart Grid Information Model standard. This
Current existing and proposed U.S. flammability standards for soft furnishings such as mattresses and upholstered furniture specify a standard cigarette as the ignition source in smoldering resistance performance tests. With the prevalence of reduced
The fundamental load combination requirements for strength design (or load and resistance factor design) appearing in Section 2.3 of ASCE Standard 7-10 advance those first developed and implemented in 1982, which since have achieved a state of maturity and

Development of the hydrogen economy will require a better understanding of the potential for fires and explosions associated with the unintended release of hydrogen within a structure. The ability to predict the mixing and dispersion behavior of hydrogen
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this test method, a lit cigarette is laid on multiple layers of filter paper, and the observer identifies whether the cigarette burns
The importance of the structural integrity of the exit stairway enclosures was clearly shown by the collapse of the World Trade Center Towers. The investigation report of the National Institute of Standards and Technology recommended that the design

Occupant descent down stairwells during building evacuations is typically described by measureable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these
This report summarizes the results of NIST research on the use of elevators during fire emergencies conducted as part of a cooperative effort funded in part by the U.S. General Services Administration (GSA).
