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.  

Best Paper at IfireSS in Naples Italy

Pool fire testOur research team traveled to Naples Italy to attend the IfireSS conference. Ben Nicoletta presented his paper to a  keen audience. The paper, Performance of Gfrp stay-in- place Form work for Bridge Dec ks after Real and Simulated Fire Damage (download herewas an interesting work with collaboration from University of Waterloo and Queen’s University. It is a preliminary study which we are currently developing into a larger project. Ben’s hard work paid off and he won best paper at the conference. Currently Ben is interning in a joint research collaboration with the global consultancy firm Entuitive (via graduate Matt Smith). Ben was supported at the conference by research team students Hailey Todd and Chloe Jeanneret. Chloe is performing an internship with Dr. Guillermo Rein’s Haze Lab at Imperial College and the trip was not too far for her. Hailey is working on stadium design.

With any conference the social program was great. We were able to explore many archaeology sites in Naples., here Hailey uses a selfie stick the way it was meant to be used, peaking behind a closed gate to look at a 2000 year old stairwell!

Fire and Materials Journal

Fire and materials 3Very exciting to announce that effective this year I am joining John Wiley’s journal, Fire and Materials as an Associate Editor. In this role I will be considering mainly the structural materials papers. Fire and Materials is one of the more older peer reviewed journals for our research community beginning in 1976. The journal is led by Steven Grayson. More information is to come on this initiative. For now be sure to check out my own Fire and Materials paper on the Creep of Prestressing steel which can be downloaded here .
