Abstract
This paper presents a study made in order to find different optimal configurations of positioning fluid dampers on high buildings for dissipating the seismic energy. The study was made using Finite Elements Method and ANSYS program, on a ten stories building structure. The first step of this optimization process is to consider the fluid dampers having linear damping properties in order to achieve a quicker convergence of the solutions. In order to obtain the influence of the dampers configurations on the structure damping there were made multiple different configurations of dampers positioned on different locations on the building. All these models were analyzed using modal analysis and it was obtained the modal damping of the building structure for the first vibration modes of the structures for each configuration. The graphics obtained can be used for achieving different degrees of seismic energy dissipation for the analyzed building.
