墙式阻尼器等效柱模型及附加阻尼比参数分析

Equivalent column model and Additional damping ratio parameter analysis on wall-type damper

为指导墙式阻尼器的结构设计和分析,提出了模拟墙式阻尼器刚度的等效柱模型计算方法,针对墙式阻尼器布置位置对附加阻尼比的影响进行参数分析,并结合工程经验总结了墙式阻尼器的设计和分析流程。结果表明:等效柱模型可以较好模拟墙式阻尼器的刚度;当阻尼器布置于中间位置时,其为结构提供阻尼比的效果略优于外侧;阻尼器所在楼层的位移角越大,其所提供的阻尼比也越大。

The method of equivalent column model was proposed for guiding wall-type damper design.Parameter analysis was made to find out the effects of damper locations on addition damper ratio.The results showed that the equivalent column model could simulate the stiffness of wall-type damper.When damper were at inside,addition damper ratio were better than outside.The bigger floor drift offers the better addition damper ratio.
