CFSRC student and postdoctoral researchers shared their latest research at the CFSRC Summer Symposium on 26 and 27 May 2020. Thirty-four participants enjoyed a deep dive into cold-formed steel and related research – focusing the first day on earthquake engineering and the second day on broader topics in thin-walled structural research. The Symposium was held online and hosted by CFSRC Director Ben Schafer and moderated by CFSRC Investigators: Hannah Blum, Matt Eatherton, Kara Peterman, and Cheng Yu. In addition to the Zoom meeting an active conversation was maintained throughout the symposium on the cfsrc slack page.
The idea for the Symposium was borne out of the loss of conferences and sharing of research due to the global pandemic. The notion was enthusiastically received by the CFSRC investigators and led to a large degree of interest from the CFSRC student researchers. The interest from the students led to an exceptional list of talks:

All of the talks were excellent, and of course some highlights stood out as well. This timeline slide from Mohamed Afifi on a specially detailed HSS brace was a first day favorite.
As was this excellent summary of recent fastener tests by Fani Derveni. Six small multiple response slides on the same slide – was no problem in the online format – so much information was packed into these 10 minute talks.
Lots of wonderful talks on Day 2 as well, it is unfair to mention just a few, but everyone was interested in Yu Xia’s Artec scanner and Haoran Wang’s talk on imperfection sensitivity in cylindrical shells was especially nice, here’s just a tidbit:
The online format was new for everyone involved but had a number of interesting advantages. For one, a large group from across the U.S. (and even some students that were currently abroad) were all able to participate. Second, the audio quality was great and the visual quality even better – it was easy to see fine details on the presenter’s slides – details that would be lost in a typical live conference setting with a projector. One attendee noted that it was nice to see everyone’s faces during the talks – instead of the back of people’s heads.
The Symposium ended with an homage to the most ubiquitous of cold-formed steel members, the humble lipped channel:
