| 摘要： | The paper studies the tuned mass damping system and the active mass damping system as a means of earthquake protection for highway bridges. It is concluded that an active mass damping system can uniformly reduce the response of a bridge to earthquakes for any input motion, but the system is applicable only if the energy source for the system is guaranteed even during earthquakes. Although the system is expected to improve the seismic performance of highway bridges significantly, the main obstacle is the large amount of energy required for driving the mass in the active mode. |
