This book presents a systematic introduction to particle damping technologies, which can be used to effectively mitigate seismic-induced and wind-induced vibration in various structures. Further, it offers comprehensive information on the latest research advances, e.g. a refined simulation model based on the discrete element method and a simplified simulation model based on equivalent principles. It then intensively studies the vibration attenuation effects of particle dampers subjected to different dynamic loads; in this context, the book proposes a new damping mechanism and global'' measures that can be used to evaluate damping performance.

Moreover, the book uses the shaking table test and wind tunnel test to verify the proposed simulation methods, and their satisfactory damping performance is confirmed. To facilitate the practical engineering application of this technology, optimization design guidelines for particle impact dampers are also provided. In closing, the bookoffers a preliminary exploration of semi-active particle damping technology, which holds great potential for extension to other applications in which the primary system is subjected to non-stationary excitations.

Offers a detailed introduction to and comprehensive description of particle damping technologies used in civil engineering Provides a promising new approach to the mitigation of earthquake-induced and wind-induced vibrations in high-rise buildings Systematically presents a theoretical analysis and practical simulation methods for particle impact dampers Demonstrates extensive shaking table tests and wind tunnel tests on particle impact dampers applied to civil structures
