THE VALUE OF THE VISCOUS FLUID DAMPERS FORCE RELATIVE TO BUILDING HEIGHT
Abstract
This paper presents the results of research carried out to determine the variation of viscous fluid dampers force as a function of building height. For this study, two damping percentages of relative level displacements, 40% and 50%, were considered. The study was carried out using a research-based software program made by Ionescu and Negru that involves a linear dynamic analysis based on a set of seismic accelerograms. Two buildings were considered, one with 11 floors and the other with 6 floors. The results of the study showed that the viscous fluid dampers force is reduced by approximately 72% for the 6-story building compared to the 11-story building, regardless of the damping percentage chosen for the analysis.
