应用粘滞阻尼器的Benchmark高层结构地震反应分析

摘要

The liquid viscous damper(LVD) can give big force to the structure, and the additional mass and static stiffness is very small. The LVD can effectively reduce the response and damage of structures. The vibration control effect of Benchmark high-rise structure with proper setup LVD is design and study. The seismic responses under three waves are analysed, and the research show that the LVD can reduce the base shear, displacement and acceleration of the structure.%粘滞阻尼器(LVD)对结构的附加质量很少,静态刚度为零,动荷载作用下又会提供很大的阻尼力,结构的动力响应能够得到很好的控制.为研究在高层Benchmark结构中设置LVD阻尼器的控制效果,在结构层间设置合理的粘滞阻尼器,仿真分析了3条典型地震波作用下结构的减震效果,结果表明合理应用LVD可以有效控制高层结构的基底剪力、位移反应和加速度反应.
