阻尼减震结构反应谱法计算若干问题

Some Issues on Response Spectra Method in Analyzing Damper-Adde d Structures

讨论了反应谱法计算减震结构所存在的主要问题,指出单纯使用加速度反应谱是不够的,提出联合采用加速度谱、速度谱和位移谱才能较好地分析阻尼减震结构。文中示例计算表明,采用线性阻尼器的减震结构,在阻尼器分布较均匀且阻尼比不大时,可以近似采用加速度谱、速度谱和位移谱来计算。

This paper points out that only using accel er ation response spectra is not enough for analyzing structures with supplemental energy dissipation devices, and that for analysis of such structures it is appro priate applying simultaneously acceleration response spectra, velocity response spectra and displacement response spectra. Three examples are given to show appl ication of the method.
