［摘要］建筑物中设置耗能阻尼器能有效地耗散地震能量，降低结构的地震作用，避免或减小主体结构的损伤。金属阻尼器和黏滞阻尼器对地震作用下的结构具有较好的减震效果，在国内外项目中得到了广泛应用。基于工程实例，对在结构中设置单一阻尼器和同时设置位移相关型和非线性速度相关型阻尼器的两种不同的消能减震方案进行反应谱和动力时程分析，通过对附加阻尼比、层间位移角、层剪力、阻尼器抗震性能等参数的对比，比较各方案的减震效果，并提出相关的设计要点，为消能减震设计提供有益的参考。

Abstract:Arranging the energy-dissipated dampers in the buildings can effectively dissipate seismic energy, reduce seismic action on the structure and avoid or reduce the damage on the main structure. Under the seismic action, the metallic damper and viscous damper have good damping effect on the structure and have been extensively used at home and abroad. Based on the engineering example, analysis of response spectrum and dynamic time-history analysis were conducted on two different energy dissipation schemes including a scheme with a single damper and a scheme with both displacement dependent and  nolinear velocity dependent dampers. By comparing parameters of additional damping ratio, interlayer displacement angle, layer shear and seismic performance of dampers, damping effects of the schemes were compared, and related design points were proposed to provide a useful reference to energy dissipation design.

Keywords:metallic damper; viscous damper; additional damping ratio; energy dissipation; dynamic time-history analysis
