摘　　要：为了探究环形剪切软钢阻尼器在受控结构中的位置优化,提出了结构阻尼器减震率灵敏度的概念,在MATLAB中以3种地震波作用下的混凝土框架结构为研究对象,计算结构在水平地震加速度激励下的位移时程响应,得出了每层结构对阻尼器的减震率灵敏度,以层间位移角不超限为优化目标,通过撤去减震率贡献较低楼层的阻尼器实现对阻尼器的位置优化,同时在相同条件下使用逐层布置法对受控结构进行环形剪切软钢阻尼器的位置优化。结果表明,文中优化效果与逐层布置法一致,证明了此方法的可行性,优化后结构各项位移均有明显的降低,其中最大层间位移角降低了72%,El-Centro波下的结构顶层52号节点位移降低了70.81%,Taft波下的优化布置方法明显优于逐层布置法。In order to explore the position optimization of annular shear soft steel damper in the controlled structure,the concept of structural damping rate sensitivity was proposed.The optimization of the damper of the controlled structure was realized through a series of analysis and calculation.The results showed that the optimization effect was consistent with the layer by layer layout method,proving its feasibility.The maximum interlayer displacement angle was reduced by 72%and the displacement of the top 52 node under El-Centro wave was reduced by 70.81%.The optimized layout method under Taft wave was obviously better than the layer by layer layout method.
