［摘要］采用屈服強(qiáng)度倍數(shù)法和等效線性化法研究附加金屬阻尼器的消能減震結(jié)構(gòu)的設(shè)計(jì)方法，用這兩種方法分別計(jì)算結(jié)構(gòu)附加金屬阻尼器的優(yōu)化阻尼量，對(duì)附加阻尼消能減震結(jié)構(gòu)進(jìn)行定量分析。將兩種方法計(jì)算的優(yōu)化阻尼量附加于原結(jié)構(gòu)上進(jìn)行時(shí)程分析并研究其減震效果，消能減震結(jié)構(gòu)的位移、速度、塑性率及主結(jié)構(gòu)承受的剪力值都有一定的減小，說明所得的消能減震結(jié)構(gòu)的減震效果優(yōu)于原結(jié)構(gòu)。兩種計(jì)算優(yōu)化阻尼量的方法都有可參考性，研究結(jié)果為消能減震技術(shù)的推廣使用打下基礎(chǔ)。

Abstract: The methods of the multiple yield strength of structure and equivalent linearization were researched to discuss the design of energy dissipation structure. The optimal damping amount of structure with additional steel dampers was calculated by these two kinds of methods, and the quantitative analysis was done. The effect on the structure with the optimal damping amount which was calculated by these two methods was discussed. The values inculding the displacement, the speed, the plastic ratio and shear force of the main structure were less than the original structure. The results of both two methods can be referenced by designers, and it could be beneficial for the promotion of energy dissipation.

Keywords: energy dissipation; steel damper; time history analysis; equivalent linearization; optimal damping amount
