Abstract

This paper presents the simulation of the influence of viscoelastic fluid dampers, with nonlinear damping properties, on damping property of a ten stories building structure. The study was made using Finite Elements Method and ANSYS program, on a 3d F.E.M. model. In order to obtain the influence of different types of damping nonlinearities of the viscoelastic fluid dampers on the damping property of the entire structure, there were made different types of simulations using modal analysis and seismic time history analysis. The graphics obtained can be used for determining the nonlinear features of fluid dampers for achieving different degrees of seismic energy dissipation for the analyzed building.
