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.

Research News for December 2017

Its been a busy few months. We gear up for the York University move in January. Our recent news includes:

Our team has won a number of recent research awards. Lauren Folk (now a graduate student on our team) won the Adjeleian Allen Rubeli Award Best undergraduate thesis 2017 at Carleton this fall. Her work is a collaboration with ARUP Fire that studied care home evacuation. We received three undergraduate research scholarships to study: Poverty in Canada, Timber in fire and GFRPs.

Heritage Timber, Tree Rings, and Fire

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.  

GFRPs, Heritage Timber, Education, Sustainable Concretes, Performance Based Fire, New Instruments and More!

Summer conferences

We have an exciting two weeks ahead. The research team will be visiting 4 conferences in the coming weeks to present 6 presentations. In addition we will have a 7th presented at ASFE and this will be announced at a later date. The below are brief descriptions of each. Open access versions will appear at a later date.

CSCE Symposium in Vancouver (May 31st to June 3rd)

Mass Heritage Timber Performance in Fire presented by Arlin Otto. The paper looks at a comparison of timber performance in fire of three unique types of timbers. The paper will also discuss adhesive bleeding seen in LVL panels .

Engineered Timber and Fire

san-fran
The Fire and Materials Conference will be held this February in San Francisco USA.

We have two papers being presented by students at this year’s Fire and Materials Conference in San Francisco:

  • Comparing timber adhesive shear strength properties after fire damage 
  • Laminated veneer lumber plated connections in fire

Engineered timber is built up using adhesives. These adhesives tend to begin to break down at temperatures around 200C. The first paper presented will represent an critical evaluation of adhesive break down from heat beyond
