| 中文摘要: |
| 附加粘滞阻尼可以增加结构阻尼，有效减小结构的地震响应，应用于既有框架结构，减震作用
显著。文章通过降低地震程度，确定附加阻尼比，估算需要附加粘滞阻尼器的数量，计算附加阻尼比，
并依据附加阻尼比对结构进行验算，获取配筋信息后对仍不满足配筋要求的构件进行加固；以既有框
架结构为例，运用粘滞阻尼器进行减震加固设计，使其结构能够满足抗震要求。 |
| 英文摘要: |
| The application of the additional viscous damper increases structural damping and effectively reduces seismic response of the structure, resulting in a remarkable function of shock absorption. The author determines the additional damping ratio according to the extent of seismic reduction，estimates the number of required additional viscous dampers and calculates the additional damping ratio with which calculation of the structure can be verified and information can be obtained for necessary steel reinforcement. The author takes the existing framework as an example and uses viscous damper for the design of shock absorption and reinforcement so as to meet the requirement of reducing seismic effect. |
