Passive Energy Dissipation Systems for
Structural Design and Retrofit
by M.C. Constantinou, T.T. Soong and G.F. Dargush
In recent years, serious efforts have been undertaken to develop the
concept of energy dissipation or supplemental damping into a workable
technology, and a number of these devices have been installed in structures
throughout the world. This monograph introduces the basic concepts of passive
energy dissipation, and discusses current research, development, design and
code-related activities in this exciting and fast expanding 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
- 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.
