Two books on Load Testing of Bridges

I published two books as an editor on the topic of Load Testing of Bridges: Load Testing of Bridges: Current Practice and Diagnostic Load Testing and Load Testing of Bridges: Proof Load Testing and the Future of Load Testing.

Besides the work involved with contacting all authors and making sure everything gets submitted on time, I also contributed as an author to about half of all chapters in these two books. It’s been a long process (three years in total!), but I’m quite happy with the final product – and extremely grateful to all authors who dedicated time and effort to writing their chapters!
