利用粘滞阻尼器对工程结构进行减震是耗能减震方法中最有效的新型抗震技术之一。
Energy dissipation is a new kind of antiseismic technology. Structural shock absorption by viscous dampers is one of the most effective energy dissipation methods.
通过和单自由度线性弹簧-质量-阻尼系统进行比较，得到该带裂缝梁结构的等效自然频率和等效粘滞阻尼比。
The equivalent viscous damping ratio and the equivalent natural frequency are obtained by comparing the system with a purely linear, spring-mass-damper system of single freedom.
结果表明，粘滞阻尼器能有效地消耗地震输入能，减小结构地震响应。
The results indicate that viscous dampers consume earthquake input energy effectively, and reduce the earthquake response of the structure.
