对某续建加固项目进行了普通钢支撑方案和黏滞阻尼支撑方案的对比,给出了黏滞阻尼器的布置形式和设计参数,通过ETABS计算分析表明设置黏滞阻尼器能显著降低结构的地震响应,提高结构抗震性能,减小结构加固量。
對某續建加固項目進行瞭普通鋼支撐方案和黏滯阻尼支撐方案的對比,給齣瞭黏滯阻尼器的佈置形式和設計參數,通過ETABS計算分析錶明設置黏滯阻尼器能顯著降低結構的地震響應,提高結構抗震性能,減小結構加固量。

Common steel brace scheme and viscous damper scheme for the continued strengthening project were compared .The layout and design parameters of viscous dampers were given .Elastic analysis of both schemes was carried out using ETABS .The results show that structure responses can be effectively reduced by adding viscous dampers , the performance objective can be verified and the strengthening quantity can be re-duced .
