【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.更多还原
