在眾多消能、減震的控制元件中,液流阻尼器能有效地增加結構物的阻尼比進而提高結構物的防震能力,可以說是經濟且有效的消能器之一。為了有效預測液流阻尼器產生的阻尼效果,本文藉由流體力學理論分析,配合試驗數據,建立一套阻尼係數經驗式。分析結果顯示此經驗公式,確能近似模擬在不同環境、不同動黏滯性液體組合下的阻尼係數,為液流阻尼器的實際應用提供一簡便可靠的分析模式。
Among energy-dissipating and seismic-response controlling systems, fluid viscous damper has been recognized as an effective and economic device to increase structural damping ratio and reduce seismic shock responses. This paper attempts to establish an experimental damping coefficient model by employing a hydrodynamic analysis and experimental data. The investigation shows that this experimental damping coefficient model can simulate the damping coefficient under different temperature conditions and kinematics viscosity, providing an effective and reliable analytic model for the application of fluid viscous dampers.
