对拟负刚度与粘滞阻尼混合减振结构的动力特性与减振效果进行了研究。首先，通过加速度放大系数和位移放大系数对拟负刚度与粘滞阻尼混合减振结构的动力特性进行分析。其次，通过反应谱对地震作用下拟负刚度与粘滞阻尼混合减振结构的减振效果进行分析，并与粘滞阻尼减振结构的减振效果进行比较。研究结果表明：拟负刚度控制能够延长结构的等效周期；当结构周期较长时，拟负刚度与粘滞阻尼混合减振结构对绝对加速度和相对位移的减振效果好于粘滞阻尼减振结构。

Dynamic characteristics and control performance for structures with pseudo-negative stiffness and viscous dampers are studied. First, dynamic characteristics are analyzed by transmissibility and dynamic magnification factor of structures with pseudo-negative stiffness and viscous dampers. Second, control performance for structures with pseudo-negative stiffness and viscous dampers subject to earthquake excitation is studied by response spectrum, and it is compared with control performance for structures with viscous dampers. The results show that pseudo-negative stiffness control system can change equivalent period of structure; control effects of absolute acceleration and displacement for structures with pseudo-negative stiffness and viscous dampers are better than those of structures with viscous dampers when period is longer.
