［摘要］为研究高烈度区框架结构装设非线性黏滞阻尼器减震效果，以某典型框架结构工程实例为背景，输入地震波进行时程分析。以楼层侧移、层间位移角、楼层剪力为减震控制目标，分析结果表明，装设黏滞阻尼器的结构减震效果明显，阻尼器在不同的工况下滞回曲线均匀饱满，呈现典型的非线性速度型阻尼器特征，分析结果对于黏滞阻尼器在高烈度区的应用与推广具有一定的参考价值。

Abstract: To study the vibration effects of frame structure with nonlinear fluid viscous dampers in highly seismic area. A typical frame structure with and without dampers was modeled and analyzed, then time history analyses were performed under earthquake records. Make the vibration control with the story displacement, story drift and story shear force. Analysis results show that the shock absorption effects are obvious, the energy dissipation hysteresis cures of viscous dampers are all rather full under different cases, and display the typical characteristic of velocity-dependent dampers. The analyses result provides a valuable reference to apply and popularize the viscous dampers in high fortification intensity site.

Keywords: high fortification intensity site; viscous dampers; frame structure; time history analyses
