As previously discussed here, every year the University of Bath holds a student conference, where their bridge engineering students are encouraged to each critique an existing structure and present a technical paper. It seems to be a near-unique exercise in the UK, and something I think deserves considerable praise.
Their 2009 event has now been held, and the papers are online. 39 different structures are featured in total, and the papers generally make for an interesting read, especially as in some cases they have had access to information from the designers not otherwise in the public domain
Is your bridge there? What did the students think?
