Fire Evacuation of People with Mobility Impairments Using Elevators

September 28, 2015
Author(s)
Kathryn M. Butler, Susanne M. Furman, Erica D. Kuligowski
The Final Report on the collapse of the World Trade Center (WTC) Towers recommended that tall buildings be designed for timely full-building evacuations from both building-specific and large-scale events. Since the WTC study, several project efforts have

Modelling the vertical UL 94 test: Competition and collaboration between melt dripping, gasification and combustion

June 24, 2014
Author(s)
Florian Kempel, Bernhard Schartel, Julio M. Marti, Kathryn Butler, Riccardo Rossi, Sergio R. Idelsohn, Anja Hofmann
An experimental and numerical investigation of the impact of the additives bisphenol A bis(diphenyl phosphate) (BDP) and polytetrafluoroethylene (PTFE) on the fire behaviour of bisphenol A polycarbonate / acrylonitrile butadiene styrene (PC/ABS) in the

Fire Characteristics of Steel Members Coated with Nano-Enhanced Polymers

March 1, 2014
Author(s)
Kathryn M. Butler, Alexander H. Cheng, Christopher Mullen, Ahmed Al-Ostaz
Applying a polymeric coating on steel members has been demonstrated to be an effective countermeasure for the threat of blast on building and other structures. The development of a blast-resistant coating for steel with good characteristics in a fire would

Report on High-Rise Fireground Field Experiments

April 10, 2013
Author(s)
Jason D. Averill, Lori Moore-Merrell, Raymond T. Ranellone Jr., Craig G. Weinschenk, Nicole Taylor, Randy Goldstein, Robert Santos, Doug Wissoker, Kathy Notarianni, Kathryn Butler
In order to balance community expectations with limited resources, the fire service and community leaders require scientific data that quantifies the effects of changes in fire service deployment on the safety of the public and firefighters. This report

Assessment of Factors Affecting Fire Performance of Mattresses: A Review

September 3, 2012
Author(s)
Rick D. Davis, Shonali Nazare, Kathryn M. Butler
An in-depth analysis of U.S. residential fire statistics shows that although the total number of fires and deaths due to mattress fires has dropped as a result of several regulatory approaches, the mattress/bedding fires continue to account for one of the

Developing Emergency Communication Strategies for Buildings

March 12, 2012
Author(s)
Erica D. Kuligowski, Steve M. Gwynne, Kathryn M. Butler, Bryan L. Hoskins, Carolyn Sandler
The purpose of this document is to provide the foundation for the development of a guidance document on emergency communication message content and dissemination strategies. The document answers three major questions regarding emergency communication

Structural and Electromagnetic Scenarios for Firefighter Locator Tracking Systems

September 1, 2011
Author(s)
Anthony D. Putorti Jr., Francine K. Amon, Kathryn M. Butler, Catherine A. Remley, William F. Young, Christina Spoons
One of the most important aspects of effective firefighter response to an emergency event is awareness of the location of the firefighters involved, especially in cases with limited visibility due to darkness, heavy smoke, or unfamiliar and changing

A Flame Model for Melting and Dripping Polymers

July 5, 2010
Author(s)
Kathryn M. Butler, Sergio R. Idelsohn, Julio M. Marti, Eugenio Onate, Riccardo Rossi
The versatility of polymeric materials, as demonstrated in such features as high strength, low weight, ease of processing, and capability to form into complex shapes, have led to their widespread industrial application in aircraft structures

Modeling Thermoplastic Melt Spread Over Different Flooring Materials

July 5, 2010
Author(s)
Kathryn M. Butler, Eugenio Onate, Riccardo Rossi, Julio M. Marti, Sergio R. Idelsohn
The effects of the thermal properties of three flooring materials on the spread rate of polymer melt over the surface were studied using a model based on the Particle Finite Element Method (PFEM). The high thermal conductivity of steel keeps the steel

Numerical Simulation of Polymeric Materials in UL 94 Test: Competition Between Gasification and Melt Flow / Dripping

July 5, 2010
Author(s)
Kathryn M. Butler, Florian Kempel, Bernhard Schartel, Anja Hofmann, Eugenio O?, Sergio R. Idelsohn, Riccardo Rossi, Julio M. Marti
The capability of the Particle Finite Element Method (PFEM, developed by CIMNE) to model the complex fire behaviour of polymers in the UL 94 scenario was investigated. For validation, a series of four PC/ABS blends were chosen, which covered different UL

Melting and Spread of Polymers in Fire with the Particle Finite Element Method

February 19, 2010
Author(s)
Eugenio Onate, Riccardo Rossi, Sergio R. Idelsohn, Kathryn Butler
A new computational procedure for analysis of the melting and flame spread of polymers under fire conditions is presented. The method, termed Particle Finite Element Method (PFEM), combines concepts from particle-based techniques with those of the standard
