Dynamics of Structures

Summary: The Best!
Review: I am a graduate student in earthquake engineering and structural dynamics. I have almost all of the books that are out there on the subject. I find this book to be the best. It is more advanced than other books on the subject (e.g. Chopra, Clough&Penzien, Tedesco et al., etc.) but also more comprehensive and thorough.
My only objection is its outrageous price. I find it completely ridiculous to pay $195, and that is why I decided to actually borrow and constantly renew the book from the library and not buy it. It is sad that such a great book will lose many prospective buyers because of its high price. Of course, you can buy the paperback for $95--which I personally think is also an outrageous price to pay for a paperback.
Bottom line: If money is not an issue for you, go ahead and buy the best book in structural dynamcics out there.

Summary: Unbelievably through and easy to use as a reference...
Review: Just like his teaching, Humar's book is straight forward and no-nonsense. This man is THE prof to have for complexe subject matter and his text is just the same: THE reference for dynamic analysis of structures. Presents all the relevant information you require, with easy to follow examples and a clarity we all wish was the standard for engineering publications. I have not even taken this as a course text, but looked into and purchased as a desk reference.... wound up reading a good portion of the book out of personal interest. There is a good review available at http://pubs.nrc-cnrc.gc.ca/rp/rppdf/l02-107.pdf . Take a look if you want another opinion.
