After the Alarm Sounds: How We Got Here, Where We Are, and Where We Should Go

April 1, 2011
Author(s)
Jason D. Averill, Erica D. Kuligowski, Richard D. Peacock
This article reviews the history of egress design and code requirements in the United States, describes the current state-of-the-art in egress design and modeling, and offers a strawman research agenda for future egress research.

A Review of Building Evacuation Models, 2nd Edition

November 1, 2010
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Bryan L. Hoskins
Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculations to assess life safety, and in

Building Occupant Egress Data

August 27, 2010
Author(s)
Richard D. Peacock, Erica D. Kuligowski
Data on people movement on stairs were collected from 9 office and residential building evacuations in the United States. The buildings involved in this study range from 6 stories to 62 stories in height. The data were collected by positioning video

Representing Egress Behaviour in Engineering Terms

June 16, 2010
Author(s)
Steve M. Gwynne, Erica D. Kuligowski, Daniel Nilsson
When using engineering tools to calculate RSET, the engineer must have sufficient expertise to identify actual human factors that will influence the outcome of an evacuation in a particular situation. The engineer must then represent these factors in the

Occupant Behavior in a High-rise Office Building Fire

June 10, 2010
Author(s)
Erica D. Kuligowski, Bryan L. Hoskins
Survey responses from occupants involved in a 32-story high-rise building evacuation during an actual fire were collected and analyzed to study the pre-evacuation period. Multiple regression models were used to test whether specific occupant, building, and

Application Modes of Egress Simulation

February 1, 2010
Author(s)
Steve M. Gwynne, Erica D. Kuligowski
The evacuation process is influenced by historical events. These can reflect previous incidents, training, and the routine use of the structure. These need to be considered during the design process as they will influence occupant behavior. In addition

The Need for Behavioral Theory in Evacuation Modeling

February 1, 2010
Author(s)
Erica D. Kuligowski, Steve M. Gwynne
This paper posits the need for comprehensive theories about human behavior in fire evacuations. These would be of value in and of themselves to improve training, education, and future data collection efforts, but would also allow for a complete behavioral

The Human Side of Mass Notification

January 8, 2010
Author(s)
Erica D. Kuligowski
On February 19, 2009, the National Institute of Standards and Technology (NIST) held a Federal Workshop on Mass Notification Messages. Participants from 12 federal agencies attended to discuss issues surrounding warning the public, building occupants, and

Compilation of Data on the Sublethal Effects of Fire Effluent

August 28, 2009
Author(s)
Erica D. Kuligowski
The NRC is developing guidance for performing quantitative human reliability analysis for post-fire mitigative human actions modeled in a fire probability risk assessment. In some of the scenarios, operators are assumed to be exposed to the fire effluent
