Particle Damping Technology Based Structural Control
Author(s)/Editor(s): Xilin Lu Sami F. Masri Zheng Lu | Size: 20 MB | Format:PDF | Quality:Original preprint | Publisher: springer | Year: 2020 | pages: 375 | ISBN: 978-7-111-59964-7 - 978-981-15-3499-7 - 2366-2603 - 2366-259X
In recent years, natural disasters, such as earthquakes and typhoons, have occurred frequently, causing serious damage to the structure. In order to enhance the resistance of structures against natural catastrophes, especially to attenuate their structural response under earthquake and wind loads, vibration control technology is applied on structures as an effective method. Particle damping technology is a kind of vibration reduction technology which consumes the vibration energy of the system by friction and impact between tiny particles filled in a finite enclosed space of the vibration cavity. It has been widely used in mechanical engineering, aerospace engineering and other fields, and its application on civil engineering has been expanding.
The Chinese Book is funded by National Science and Technology Academic Monograph Publishing Fund (2017). The English version is the update version.
This book systematically introduces particle damping technology, which can be utilized to effectively mitigate the seismic-induced and wind-induced vibration of various structures. The research achievements pertaining to this technology are comprehensively presented in this book. The 9 chapters in the book can be divided into 3 main aspects, first of all, in Chaps. 1 and 2, the book gives a detailed introduction and comprehensive description of structural vibration control technology and particle damping technology utilized in civil engineering, and provides a newly efficacious approach for the mitigation of earthquake-induced and wind-induced vibrations generated in high-rise buildings. The second part is illustrated in Chaps. 3–7, systematically theoretical analysis and practical simulation method for particle impact dampers are proposed, as well as demonstrated the extensive shaking table test and wind tunnel test on particle impact dampers applied to civil structures, which are conducive to understanding the damping mechanisms and optimal working conditions of particle impact dampers. In Chaps. 8 and 9, profound discussions are carried out on the future perspectives of particle damping technology, especially emphasized on studying and developing semi-active particle damping technology, and established the guidelines for optimization design of particle impact dampers. Some distinct features of this book can be summarized as follows:
• The elaborated simulation model based on discrete element method and the simplified simulation model based on equivalent principles are demonstrated, the models are verified by corresponding experimental results.
• The steady-state responses of particle impact dampers under various scenarios are illustrated.
• The vibration attenuation effects of particle dampers subjected to different dynamic loads have been intensively studied, by which the damping mechanism and the “global” measures that are used to evaluate the damping performance are proposed.
• The shaking table test and wind tunnel test have been conducted to verify the proposed simulation methods, and the satisfactory damping performance of
particle dampers has been corroborated.
• The optimization design guidelines of particle impact dampers are provided.
• The semi-active particle damping technology in which the primary system is subjected to non-stationary excitations is preliminary explored.

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.
