I studied this book 34 years ago, and remember it as my favourite text, even though I never applied much of the material (I ended up going into environmental, not structural engineering.) Many engineering texts are a collection of theorems and facts put together in a more or less systematic fashion, but without a clear underlying story or thread. 34 years later I still remember the logic of this text and its power: balancing forces, understanding and respecting geometric constraints, and understanding and applying.
