Passive Energy Dissipation Systems for Structural Design and Retrofit
MetadataShow full item record
This monograph introduces the basic concepts of passive energy dissipation and discusses current research, development, design and code-related activities in the field. The authors provide basic definitions for passive energy dissipation systems and provide basic design principles governing their use. Mathematical modeling, recent developments, and modern applications of the following devices are covered in depth: Metallic Dampers, Viscoelastic Dampers, Tuned Mass Dampers, Friction Dampers, Viscous Fluid Dampers and Tuned Liquid Dampers. The final chapter in the monograph discusses semi-active control systems. Semi-active mass dampers and semi-active fluid dampers have been installed in buildings in Japan, and are discussed in some detail, along with current research in the field. Tables are provided in the appendices that detail application of passive energy dissipation systems in North America and active and semi-active systems in Japan.
