Evacuation Study of a Cultural Centre

abstracts1Our team’s recent human behaviour in fire research in collaboration with ARUP will be presented at Interflam in London, UK this July. Two of our multi-disciplinary papers represent an ongoing research project performed over the last three years: “Fire evacuation and strategies for cultural centres.” And “The effects of Linguistic Cues on Evacuation Movement Times”. In this research project we characterized three evacuations that occurred at a Cultural Centre over the course of three years. This project has been a major focus of our group for some time however one which requires significant consideration. We are now introducing the project to the fire community for the first time this summer for preliminary feedback as we continue to advance this very important project in the long term.

abstracts2Interflam is one of the leading fire conferences this year so the venue serves a great location. Part of our outputs are towards a comprehensive database of group based movement and decision making characteristics. We followed this with extensive surveying of linguistic evacuation cues at that centre conducted over several months to interrogate themes we observed. These results are being utilized to inform the development of evacuation modelling in our future work and collaborations.

Presentations of these papers will occur July 2nd, papers will be posted soon!

Stadium Pedestrian Flow Research: Emergency Fire Evacuations

Our team’s human behaviour in Stadia project in collaboration with ARUP (a multi-year NSERC Collaborative Research Development Initiative), will be presented at Interflam in London UK this July 2nd. This student led paper by Danielle Aucoin and Tim Young represents an ongoing research project performed over the last two years. To date we have studied ingress and egress behaviour in four stadiums. We have focused on Tennis, Baseball, Soccer and Football, and our preliminary results that we can share are just appearing now.

The Experiences of Women in Undergraduate Engineering

The following is a guest post by research assistant and team member, Natalie Mazur. This June, Natalie is presenting The Experiences of Women in Undergraduate Engineering at the 9th Canadian Engineering Education Association’s Annual Conference., Vancouver, Canada. The paper can be downloaded here . 

A long-standing issue in the field of engineering has been the representation of women. Of the students that pursue undergraduate studies, half are women. However, to this day, women make up only 21% of engineering undergraduate students in Canada. This number has not significantly changed in almost 20 years. Additionally, women make up only 17% of newly licensed engineers nationally. As we look higher and higher up the corporate ladder, fewer and fewer women are visible.

SFPE 12th International Conference on Performance Based Codes and Fire Design – Hawaii

Members of our team attended the SFPE fire conference in Hawaii last week. Team member Hailey Quiquero gave a fantastic presentation on modelling timber structures in fire from a FEM point of view. Her work is a collaboration with the University of Canterbury. Dr. Gales gave a presentation regarding steel connections based on team alumni Matt Smith’s work as he could not make the conference.

Timber Structure Fire Test

Our Timber research was recently published in a conference paper presented at ASFE. The paper that describes our team’s work before 2016 can be downloaded here.

Since that above paper, and last year, our research team have undertaken four new and novel Timber based projects to expand knowledge in this research area as we relocate to York University.

Heritage Timber, Tree Rings, and Fire

Post and beam
Slow burning timber construction methods  circ. 1890

The past few days we have been sorting through the structures lab after the end of the last academic year. Among the materials which we were indexing and storing were the heritage timbers that we tested for the CSCE paper (posted below). The timbers were installed in a heritage building built approximately in 1890 or so. In a retrofit of a building they were removed. We tested the timber beam first in structural loading. The beam was tested for our second year undergrads to see. Then we extracted two planks from the timber as it only had moderate damage for flame spread testing (to be compared to modern engineered lumber of the same moisture content). Since then the planks have sat. Looking at the timbers myself and Mina Li, opted to count the tree rings this week to estimate the timbers age yesterday. Relating to Canada’s 150 we were in for a bit of a shock.  

Visiting the 911 Memorial in New York

WTCOn April 22nd, as part of a break from school at the end of the term, I took in the 911 Memorial Museum in New York. Not the most uplifting story to hear on a vacation, but a place I have been meaning to visit for years. I felt the museum to be very tasteful and a very important learning piece for those to learn what exactly happened that day (but ill argue understanding is different word to use here and a word I do not think we ever will be able to associate to that day). I feel it so important that people do be aware, today’s students that i teach, were far to young to know a world pre 911, they grew up in a different world. And from that the observations that you can learn visiting are just so much more important. The museum allows you to see quite a bit in terms of artifacts (fire trucks, and even the original foundations of the the tower). But it does educate what happened.

The Next Tallest Building in San Francisco

The Salesforce Tower will soon be completed and overtake the Pyramid as San Francisco’s newest and tallest building. I had a great oppertuinity to take a stroll through the construction area early this month and decided to highlight a few aspects of what i learnt and saw.

To me when i see cities like this, i am filled with creative inspiration. Its very easy to predict what the future skyline of San Francisco will look like. Where the tall buildings will appear (note that for now special planning approval must be given in San Fran), where the heritage will be conserved etc.

Defining the Future of Fire Safety Engineering in Canada

Matt Smith successfully defended his research thesis on Steel in fire with no required revisions and was nominated for a university senate medal.

Research team member, Matthew Smith, and Engineer at global consulting firm, Entuitive, successfully defended his masters thesis: Towards a Performance-Based Fire Design Framework for Composite Steel Deck Construction in Canada . His thesis and defense were of the highest quality that there were no corrections necessary. Matt was subsequently  nominated for the university’s senate medal (he has also just been awarded the SFPE National Capital Region Chapter Scholarship in Fire Safety Engineering in Canada for his work. A big thank you to his examiners whom I would say have a combined experience of over 60 years practicing steel construction. Also a big thank you to project sponsors: CISC and Entuitive, as well as to reps from FM Global and the National Research Council, NIST for their previous feedback and contributions.

After 15 years….

20160817_144408

Its been about 15 years since the events of September 11th. I remember the day very clearly still. Reflecting on how much has changed since that day in society and our built environment is staggering. While visiting NIST this summer I had the opportunity to do some of this reflection. Largely a lot of the structural work being done there is to aim to improve the safety of our buildings. Outside their new fire lab they have preserved steel pieces from that day in a memorial. If you want to read more about the structural and human behavioral analysis of the events from that day the journal Fire Technology has a really comprehensive issue from 2013 which is a very enlightening read.
