Our fire lab funding was made official with a CFI-ORF grant this September. This funding advances equipment and technology for material study in fire and conducting data collection in HBIF studies with modern camera equipment. The grant will allow the fire testing lab at York University in Toronto, Canada to scale up fire testing technology. This tech will allow for testing using load and heat on realistic building frames to make buildings safer and more cost-efficient. A demonstration ‘blue-light’ fire test at York University was performed as part of the funding announcement by the government ministry.

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 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 .
Our research team received four NSERC USRA scholarships this summer (up from two last summer). The students (Natalie, Ben, Chloe and Seth) with these scholarships will study a variety of projects from Modelling pedestrian flow, timber design, to studying travelling fires with our international and national collaborators. These national awards at Carleton are given to undergraduate students who are excelling academically and have an interest to pursue further graduate studies.
Our graduate students Hailey Q won an Ontario Graduate Student Award, and so too did Matthew Smith as he recently won the SFPE National Capital Region Chapter Scholarship for Fire Safety Engineering for his thesis and these results are currently being distributed through the Canadian Institute of Steel Construction. In addition Arlin won Provost Scholar. In total the research team received about 36k in scholarships this past month.
Had an absolute grand time crushing Legos with Hailey Todd and the virtual ventures summer camp at Carleton University this week. Thought Id pass on some of the results we observed. Unlike the previous study conducted for the BBC where only one Lego block type was tested, we really wanted to understand what happens with Lego under a realistic building configurations and loading scenarios. So we took typical Lego blocks of 1×1, 1×2, 1×3 and 1×4 brick sizes and tested them in a loading actuator with compressive displacement control (mm per minute).
What we observed was that as the size increased so too did the ability to carry load (see graph below). Though it was not proportional to the added stud-brick for each block. We did not cap the Legos because we wanted to see the full effect. Basically the failure mechanism is as follows, the test begins with load being applied and the Lego brick ‘stud’ is pushed into the block giving a flat loading surface along the top of the block, there is a small elastic phase and then we begin to crush the Lego block (its peak load). Later we did cap the Lego and saw some interesting differences in peak load and failure pattern (see below).
We opted to use Lego as a teaching example as its a relatable building material to youths. I think its a gate way to show them just how strong materials are when you can relate them to the day to day lives, obviously we get them hooked there, and progress to crushing concrete and breaking steel much after.
