摘要 探讨了运用被动的控制装置减轻相邻结构地震动响应的机理,比较了在不同的地震波作用下粘弹性阻尼器和流体阻尼器的减震效果。将两相邻结构简化为两单自由度体系,用Voigt模型模拟连接两相邻结构的粘弹性阻尼器,用Maxwell模型模拟连接两相邻结构的流体阻尼器,分别导出了在地面白噪声激励下主结构平均振动能量最小或两相邻结构总平均振动能量最小这两个控制目标下粘弹性阻尼器与流体阻尼器的优化参数的一般表达式。运用具有不同频谱特性的三类相邻结构在ElCentro1940NS,Kobe1995和唐山地震波作用下的数值结果比较了这两种被动阻尼器的减震效果,详细讨论了导致不同控制效果的原因。 The mechanism of reducing the seismic responses of adjacent structures under earthquake by using passive coupling elements interconnecting adjacent structures is exploited in this paper. The control effectiveness by using visco-elastic damper and fluid damper is compared. The two adjacent structures are simplified into two single-degree-of-freedom systems, and the connecting visco-elastic damper is represented by the Voigt model and the connecting fluid damper is represented by the Maxwell model, respective...
