Time-history Analysis of Earthquake Response on Structure with Non-linear Fluid Viscous Damper
【摘要】 本文基于国内外现有的粘滞阻尼器性能试验和计算研究,提出单自由度非线性粘滞阻尼器的计算方法。文中给出了粘滞阻尼器非线性运动方程的解法,并运用该方法进行了大量的比较计算,研究了单自由度非线性粘滞阻尼器的动力响应特性。
【Abstract】 Based on existing established experimental modal analysis and vibration analysis techniques, a new calculation method of fluid viscous damper controlling nonlinear earthquake responses of single-freedom-of-degree (SDF) systems was proposed. The derivation of the equation governing the motion of the SDF system with a non-linear fluid viscous damper was outlined. And then, a great of calculations were carried out to study the precision of the method and the dynamics response of SDF fluid viscous damper.
