SEISMIC DESIGN OF STRUCTURE WITH NONLINEAR FLUID VISCOUS DAMPERS
This paper presents a seismic design method for existing buildings equipped with nonlinear flu-id viscous dampers (FVD). Mechanical properties of nonlinear FVD are first investigated. Equivalent linear viscous damping ratio provided by nonlinear FVD installed in buildings is introduced. Load combination factors used for evaluation the response of the supplemental damp-ing systems at the stage of the maximum acceleration are given. A simple design procedure for building incorporating nonlinear FVD is proposed based on Chinese design response spectrum, in which the damping coefficient of damper is determined according to the principle that the horizontal component of the damper force is proportional to the corresponding story shear force demand. The application of the simple procedure is illustrated using an example. It is demonstrated that the presented method is effective and straightforward for design of buildings with nonlinear FVD, particularly at the stage of preliminary design.
