［提要］  振型分析反应谱法是结构减震消能分析中的重要方法。为比较阻尼比不为5％时的反应谱与阻尼比为5％时的反应谱的情况，介绍了阻尼衰减因子B的概念，同时编制了该衰减因子与特征周期、结构自振周期及总阻尼比之间关系的表格。可方便地用于反应谱法消能减振结构的阻尼设计。

Abstract:The concept of damping reduction factor B is discussed to compare the design values of response spectra and more than 5% damping ratio. The corresponding relationships of damping reduction factor, characteristic period, self-vibration period of structure and the total damping ratio are compiled in simple tables which are convenient to be used in aseismic design for damperadded structures.
