[摘要] 钢结构自身阻尼比较小，结构变形较大，一般可以通过设置阻尼器来控制结构地震响应。本文根据粘弹性阻尼器的原理，结合粘弹性阻尼器Maxwell力学模型，使用有限元软件SAP2000对一榀高烈度地区设置了粘弹性阻尼器的高层钢框架结构进行了弹性和弹塑性动力分析。研究数据表明，粘弹性阻尼器可以有效的控制高层钢结构框架在高烈度地区的地震响应。

Abstract: Damping ratio of steel structure is relatively less,and deformation of steel structure is large. It is usually control the seisnuc response by adopting dampers. Based on the viscoelastic damper principle and the Maxwell model,elastic and elastoplastic dynamic analyses of a lugh-rise steel structure with viscoelastic dampers in high intensity areas are made by using finite element software SAP2000. The results show that viscoelastic dampers can effectively control the seismic response of lugh-rise steel structures in high intensity areas.
