摘　　要：以西安长庆石油勘探局科研楼钢结构塔楼工程为背景 ,建立了高楼屋顶上钢结构塔楼的三维空间有限元静力模型和二维串联多自由度的动力模型。讨论了高楼上高塔的振动特性以及安装粘滞性阻尼器对高塔地震响应的振动控制。研究表明 。Based on the design of the steel tower on a reinforced concrete tall building in xi'an, two analytical models were chosen in this paper. One is the two-dimensional lumped mass dynamic model and the other is the three-dimensional finite element static model. Then, the dynamic characteristics of the steel tower and the control of the dynamic response for the steel with the fluid viscous damper tower are discussed. The research results show that the fluid viscous damper for structural control can reduce the vibration response of steel tower under earthquake excitation effectively.
