Creep of Prestressing Steels in Fire

Our new paper, Creep of Prestressing Steels in fire, is now in press in the journal Fire and Materials (you can access it here; an open access version is to come). It is a great piece about prestressing steels used in Post-tensioned structures. We show how high- temperature creep is effected by the chemical composition of…

Annual Concrete Labs at Carleton

Teaching the undergrad students about emerging materials this week. To make our labs more educational this year (with massive amounts of extra safety protocols added), we conducted several concrete compression tests on conventional concrete wrapped in a carbon fiber reinforced polymer (frp). The students are able to compare their normal conventional concrete compression cylinder tests to…

Steel Stub Column Undergrad Lab

We did a very ad hoc style image correlation test using a steel stub column in the undergrad labs. Though not really an accurate way to adhere image correlation paint though, however; it was a good illustration of observing yielding and buckling effects on the column as the test progressed. Images in this video were…
