Dynamics of Structures has been well received in the 21 years since it was first published. It continues to be used as a textbook at universities in the United States and many other countries, and enjoys a wide professional readership as well. Translations in Japanese, Korean, Chinese, Greek, Spanish,Persian, and Turkish have been published. The SI version of the 4th edition was published in 2015.
Preparation of the fifth SI edition provided me with an opportunity to improve, expand, and update the book.
Chapter 20 has been expanded in a major way; Chapters 7, 9, 13, and 18 have also been expanded; Chapter 11 underwent significant revision; and Chapters 22 and 23 have been updated.
Specific changes include:
• Two new parts, B and C, have been added to Chapter 20, which is now more than twice its previous size. These additions were motivated by the increasing use of nonlinear response history analyses (RHAs) of buildings in professional practice. Discussed in Part B are several issues that arise in modeling of the overall structure as well as structural elements for nonlinear RHAs. Part C is concerned with selection and modification of recorded ground motions to define the excitations for which seismic demands on structures are to be determined by nonlinear RHAs. A “hot” topic for research since 1998, it has been included in a textbook for the first time.
• Chapter 13 has been extended to include a topic that so far has been confined to the research literature but is of practical interest: a response-spectrum-based method to estimate principal stresses in continuum structures, such as concrete dams.
• Chapters 7, 9, and 18 have been expanded to include P– analysis of gravity load effects and an introduction to their influence on the lateral response, permanent deformation, and collapse of structures.
• Chapter 11 has been revised to include recent data on damping ratios determined by system-identification analysis of motions of 203 buildings recorded during earthquakes. New recommendations for estimating damping ratios to be used in earthquake analysis of structures are presented.
• Chapters 22 and 23 have been updated to reflect the current editions of building codes for designing new buildings, and of performance-based guidelines and standards for evaluating existing buildings.
• Many new figures, several worked-out examples, and end-of-chapter problems have been added.
Using the book in my teaching and reflecting on it over the years suggested improvements. The text has been clarified and polished throughout, and a few sections have been reorganized to enhance the effectiveness of the presentation.
