摘　　要：以某教学楼的粘滞阻尼器设计为例,结合美国规范ACSE7-05[6]和中国抗震规范[5],采用了三种不同的办法计算高阻尼下的反应谱,同时对比SRSS振型叠加和用1振型加上残余振型叠加的不同叠加计算的近似高阻尼反应谱计算法的分析结果,进而利用SAP2000程序的计算结果来对各种近似高阻尼反应谱计算法进行验证。通过对各种计算进行比较探讨,望其能对粘滞阻尼减震结构的设计和规范的编制提供参考。Based on the application of the fluid viscous dampers designed for a school building with the Response Spectrum Procedures of the Chinese Seismic Code and the American Standard（ASCE 7-05）,the article adopted three different calculation methods to work out the response spectrum under high damping with the results of each method compared.Besides,it also uses the time-history analysis results with SAP2000 program to verify the various simplified response spectrum procedures with the hope of providing references for the design of damper＇s vibration control.
