Berkeley, CA, February 26, 2004 – Computers and Structures, Inc., is pleased to release the latest revision to Dynamics of Structures, 2nd Edition by Professors Clough and Penzien. A classic, this definitive textbook has been popular with educators worldwide for nearly 30 years. This release has been updated by the original authors to reflect the latest approaches and techniques in the field of structural dynamics for civil engineers.
During the past 50 years, Drs. Ray Clough and Joseph Penzien have earned pre-eminence in the engineering community, dedicating their academic lives to improving the understanding of how structures behave when subjected to nature's forces. This 700-page book represents the culmination of that work. It introduces topics suitable for advanced undergraduate students and progresses through more advanced topics, such as non-deterministic analysis of earthquake response, appropriate for the graduate student and practicing engineer.
This book belongs on every engineer’s shelf. Historically, few books in structural engineering have had as much influence on expanding the knowledge base in structural engineering. With this revision, the book remains an extraordinary tool for those teaching structural dynamics and a timely reference for those in professional practice.
Volume and educational pricing are available through Computers and Structures, Inc.

This Solutions Manual contains the solution to all the problems proposed in the text Dynamics of Structures. To solve many of these problems, the student should be very familiar with trigonometric and hyperbolic relationships, integral and differential calculus, matrix algebra, and matrix structural analysis. The student also ~as to have some knowledge of differential equations, and probability and theory of residues (these last two topics for Part IV).
The problems were solved from the first edition of the book, systematically and for no particular reason, when I was pursuing graduate studies at Berkeley in the late 70s, without haying in mind that these solutions would later be assembled in a Solutions Manual. Therefore, the way the solutions are carried out may not be optimally didactic.or elegant; however, they present the advantage of showing a step-by-step procedure that a regular student would perform in attempting to solve these problems in a homework or test framework, or simply just for fun. All the problems can be solved by hand, but in a small number of cases it was
preferred to present a solution carried out with the help of a computer progra·m or a programmable calculator. Some of the problems may be solved differently (especially in Part IV); however, the answers are correct, and almost all have been independently checked.
In order to prepare the Solutions Manual, the existing solutions for the first edition of the book were revised to C!mform to the new edition, and then transcribed into the manual's current format. This procedure was checked carefully. Nevertheless, if the reader notic~s any error, I would be pleased to be advised. Finally, I wish to thank the book's authors for allowing me to have an enjoyable time while studying in Berkeley. The transcription of the solutions was patiently done by Mr. Jose Orozco, who deserves to be given all the credit for it.
