Maxwell粘滞阻尼器耗能结构的等效阻尼分析
|
摘要
通过研究Maxwell粘滞阻尼器耗能单自由度结构的等效阻尼,运用随机平均法和基于随机平均分析完全相同的等效准则,建立了可直接应用反应谱法的上述阻尼器的等效阻尼计算公式,并给出了算例,验证了等效阻尼计算公式的合理性.
The equivalent damping of SDOF dissipation structure with Maxwell viscous dampers is studied and the stochastic averaging method is used in this paper.By using the stochastic averaging method and the equivalent criterion of stochastic averaging analysis,the analystic formulas of equivalent damping of Maxwell viscous dampers are established.And the precision for formulas of equivalent damping is verified by an example.
