[摘要]為研究高烈度區(qū)框架結構裝設非線性黏滯阻尼器減震效果,以某典型框架結構工程實例為背景,輸入地震波進行時程分析。以樓層側移、層間位移角、樓層剪力為減震控制目標,分析結果表明,裝設黏滯阻尼器的結構減震效果明顯,阻尼器在不同的工況下滯回曲線均勻飽滿,呈現(xiàn)典型的非線性速度型阻尼器特征,分析結果對于黏滯阻尼器在高烈度區(qū)的應用與推廣具有一定的參考價值。

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
