［摘要］对一座形状不规则的、纵向刚度递减的框架-剪力墙结构采用黏滞阻尼墙和软钢阻尼墙两种减震方案进行减震效果对比分析。对未减震结构、设置黏滞阻尼墙减震结构和软钢阻尼墙减震结构进行7条地震波激励下的动力响应对比分析，结果表明，两种减震方案均能有效降低结构位移响应，位移减震效果两者均达到40%，楼层层间剪力结果表明设置黏滞阻尼墙减震效果达到35.68%，而软钢阻尼墙的层间剪力与未减震结构结果一致。以上结果说明框架-剪力墙结构尽管楼层位移较小，但黏滞阻尼墙由速度耗能给结构附加较多阻尼而减小地震力。软钢阻尼墙为位移型，由于楼层层间位移较小无法提供较大的耗能能力从而未能达到较好减震效果。

Abstract: A comparative analysis of damping effect of a frame-shear wall structure installing viscous damping wall and mild steel damping wall was studied. The frame-shear wall structure was irregular and stiffness decreasing with height in the vertical direction. Seven seismic wave excitations were input to no damping structure, viscous damping wall structure and mild steel damping wall structure to get the comparative analysis of their dynamic response. The results show that both damping scheme can decrease the drift response and both of the drift damping effect can reach 40 percent. The story shear force damping effect of viscous damping wall structure can reach 35.68 percent, while the result of mild steel damping wall structure is almost the same with no damping structure. The results above show that although the displacement of the frame-shear wall structure is small, but the viscous damping wall structure with speed energy consumption can decrease the story shear force through adding more damping to the structure. Mild steel damping wall structure with displacement energy consumption can not reach good damping effect because small story displacement can not provide large energy dissipation capacity.
