摘　　要：本文阐述了粘弹性阻尼器的计算模型,对设置粘弹性阻尼器的钢筋混凝土巨型框架多功能减振结构的抗震性能进行了初步分析,研究结果表明,设置粘弹性阻尼器能够显著降低钢筋混凝土巨型框架多功能减振结构的地震反应,同时可以防止结构产生地震碰撞破坏。The calculating model of the viscoelastic damper is introduced, and th e effect of the viscoelastic dampers on the seismic performance of the multifunc tional vibration-absorption reinforced concrete mega-frame structures is studied in this paper. The results of the research show that the seismic response of th e multifunctional vibration-absorption reinforced concrete mega-frame structures with the viscoelastic dampers are mitigated greatly and the viscoelastic damper s can improve the safety performance of the structure.
