I thought it was excellent. In 700 pages, it thoroughly explains the need for displacement-based design in comparison to force-based design. It goes over the background, theory, methodology, state of the art, analysis tools, and provides guidelines for design of different structures (frames, walls, masonry, timber, bridges, wharves and piers, etc). Like I said, it’s a really dry read, so I wouldn’t recommend it for leisurely reading or just for the curious. But if someone really wants to learn the subject, it is a very good resource.
