The seismic design principle and analysis methods for building structures using fluid viscous dampers are studied in details. The layout of fluid viscous dampers, energy-dissipation brace type, seismic fortification aim and key characteristics of this technology are introduced. The additional horizontal control force of the fluid viscous dampers applied to structures, additional effective damping ratio, seismic influence coefficient and calculation method of damping coefficient matrix are presented. Two calculation methods, i.e. response spectrum method and direct dynamic time-history analysis method, are described. The practical design procedure of structural vibration energy dissipation technology is presented using fluid viscous damper.
