A Review of Risk Perception in Building Fire Evacuation

October 1, 2014
Author(s)
Max T. Kinateder, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock
Risk perception (RP) is studied in many research disciplines (e.g., safety engineering, psychology, or sociology), and the contexts surrounding the ways in which different concepts of RP are applied vary greatly. Definitions of RP can be broadly divided

Risk perception (RP) is studied in many research disciplines (e.g., safety engineering, psychology, and sociology), and the context in which RP is studied varies greatly. Definitions of RP can be broadly divided into expectancy- value and risk-as-feeling

Movement on Stairs During Building Evacuations

September 25, 2014
Author(s)
Erica D. Kuligowski, Richard Peacock, Paul A. Reneke, Emily A. Wiess, Jason D. Averill, Robert Hagwood, Enrico Ronchi, Bryan Hoskins, Michael Spearpoint
The time that it takes an occupant population to reach safety when descending a stairwell during building evacuations is typically described by measureable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn

Assessing the Verification and Validation of Building Fire Evacuation Models

September 19, 2014
Author(s)
Enrico Ronchi, Erica D. Kuligowski, Daniel Nilsson, Richard Peacock, Paul A. Reneke
To date there is no International standard on the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance, the tests presented within the

Fire Model Validation – Eight Lessons Learned

March 6, 2014
Author(s)
Kevin B. McGrattan, Richard D. Peacock, Kristopher J. Overholt
This paper provides a summary of a decade-long effort to verify and validate a variety of different fire models used in the commercial nuclear industry. The lessons learned apply to any industry in which fire models are used in a regulatory context. The

Stair Evacuation of People with Mobility Impairments

March 3, 2014
Author(s)
Erica D. Kuligowski, Richard Peacock, Bryan Hoskins, Emily Wiess
The time that it takes a population to reach safety when descending a stairwell during building evacuations is typically described by measureable engineering variables. These engineering variables include stairwell geometry, speed, density, and pre

A probabilistic approach for the analysis of stair evacuation movement data

January 1, 2014
Author(s)
Enrico Ronchi, Erica D. Kuligowski, Richard D. Peacock, Paul A. Reneke
This paper presents an innovative method to study stair evacuation data based on a probabilistic analysis of occupant travel paths. This type of approach relies on a detailed video analysis of people movement and pattern reconstruction. Conditional

The Process of Verification and Validation of Building Fire Evacuation Models

November 21, 2013
Author(s)
Enrico Ronchi, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock, Daniel Nilsson
To date, there is no International standard on the methods and tests to assess the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance

Stair evacuation of older adults and people with mobility impairments

October 31, 2013
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Emily Wiess, Bryan Hoskins
Engineers analyze occupant movement data for the safety and protection of a population during emergency building evacuations. Quantifiable variables, such as: stairwell geometry, pre-evacuation delay, occupant speed, and population density form engineering

A method for the analysis of behavioural uncertainty in evacuation modelling

July 9, 2013
Author(s)
Enrico Ronchi, Paul A. Reneke, Richard D. Peacock
Evacuation models generally include the use of distributions or probabilistic variables to simulate the variability of possible human behaviours. A single model setup of the same evacuation scenario may therefore produce a distribution of different

Simple Estimates of Combined StairWell / Elevator Egress in Buildings

March 5, 2013
Author(s)
Paul A. Reneke, Richard D. Peacock, Bryan L. Hoskins
This report is part of this effort to develop requirements for the use of elevators in tall building evacuations. It describes a simple tool to estimate combined stairwell / elevator egress time from buildings. It is based on methods developed in the

Analysis of Egress From the World Trade Center Towers on September 11, 2001

January 31, 2013
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
This paper provides an analysis of the evacuation of the World Trade Center towers culled from telephone and face-to-face interviews with survivors. A decedent analysis explores where occupants were located when each tower was attacked. Multiple regression

Evacuation of People with Disabilities on Stairs

September 18, 2012
Author(s)

The time that it takes a population to reach safety when descending a stairwell during building evacuations is typically described by measureable engineering variables. These engineering variables include stairwell geometry, speed, density, and pre

A Literature Review of the Effects of Fire Smoke on Electrical Equipment

July 31, 2012
Author(s)
Richard D. Peacock, Thomas G. Cleary, Paul A. Reneke, Daniel Murphy
A review is presented of the state of the art of smoke production measurement, prediction of smoke impact as part of computer-based fire modeling, and measurement and prediction of the impact of smoke through deposition of soot on and corrosion of

Building Occupant Safety Research 2012

May 17, 2012
Author(s)
Richard D. Peacock, Erica D. Kuligowski, Jason D. Averill
Historically, building egress systems have evolved in response to specific large loss incidents. Currently, systems are designed around a concept of providing stair capacity for the largest occupant load floor in the building with little or no

Report on Residential Fireground Field Experiments
