【Abstract】 The principle and design method of vibration energy dissipation and structural control are introduced. The conformation and energy dissipation principles of various fluid viscous dampers were studied and a kind of high-performance damper, i.e. fluid viscous damper with double guide bars, was developed and manufactured. Based on the study and experiment, it is concluded that this fluid viscous damper for vibration energy dissipation is a kind of velocity related damper without rigidity. The relationship between the damping force and the velocity is approximately linear. With fluid viscous damper, the structural vibration energy dissipation control of a high-rise building with a steel tower on its roof was carried out. The computing results prove that the fluid viscous damper can effectively reduce the structure vibration response induced by earthquake and wind. It is a high-performance structural vibration energy dissipation device.更多还原
