The Structure Separation Project is a multi-level project to assess structure-to-structure fire spread in Wildland-Urban Interface (WUI) communities. The project is divided into three phases with each phase assessing radiant and convective heat exposures

Structure Vulnerability to Firebrands from Fences and Mulch

July 23, 2020
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Wei Tang
Fences and mulch contribute to the spread of WUI fires. They act as both ignition targets and as sources that may themselves ignite nearby objects through direct flame contact and firebrand generation. The linear nature of fences gives them the capability

Flame Spread Along Fences Near a Structure in a Wind Field

October 20, 2017
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Eric Auth
Combustible fences have been identified in post-fire investigations of wildland-urban interface (WUI) fires as potential threats to homes and other structures. They may ignite due to direct fire contact or firebrands, they may conduct fire along their

Survey of the State-of-the-Art for Ocean Wave Energy Conversion Systems

February 19, 2017
Author(s)
Kathryn Butler, Marc R. Nyden, William G. Rippey
It is possible to generate electrical energy from the motion of water due to ocean tides and waves. Oceans are a much more ubiquitous source of flowing water than river gorges, and the ability to efficiently harness this energy could potentially solve many

Wind Effects on Flame Spread and Ember Spotting Near a Structure

February 6, 2017
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Glenn P. Forney, Eric Auth
In wildland-urban interface (WUI) fires, combustible materials pose a potential threat to contiguous or nearby structures. Flame spread and firebrand spotting have been studied in a series of field experiments involving fences and mulch beds under a

Perspectives of Occupants with Mobility Impairments on Fire Evacuation and Elevators

August 15, 2016
Author(s)
Kathryn M. Butler, Susanne M. Furman, Erica D. Kuligowski, Richard D. Peacock
The purpose of this report is to provide guidance for designers, building managers, and fire emergency personnel on how to improve communication, procedures, and elevator usage during fire emergencies, based on a study of the evacuation experiences of

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
