This paper presents a method of vibration response analysis of vibration controlled building frames in which turbulent liquid flow dampers sealed by viscoelastic material are incorporated. Resisting force of the damper consists of viscoelastic resistance of the sealing material and inner pressure of the liquid flowing in an orifice. Theoretical models representing both the resistances are constructed based on theory of viscoelasticity and turbulent flow rule. Resisting force term of the damper is incorporated in the equation of motion for single mass vibration system, for which time integration program is developed using Runge-Kutta method. Validity of the response analysis is demonstrated by comparison to the result of forced vibration tests of damped steel frame specimen.
