Abstract

This paper presents a study of seism analysis of a reinforced concrete frame structure with a height of B + 5S, made in order to determine the performance of the damping system with viscous fluid that equips the superstructure for buildings of medium height (15–20 m). For this, the GenEcAm program developed by the authors was used, which performs a dynamic analysis using design accelerograms. Three cases of seismic analysis were considered: structure without anti-seismic equipment, structure equipped with viscous fluid dampers with damping coefficient c = 2000 kNs/m2 and structure equipped with viscous fluid dampers with damping coefficient c = 4000 kNs/m2. For these three cases of analysis, a set of nine design accelerograms made with the MSIMQKE program [1] was considered, three for each value of the corner period Tc = 0.7 s, Tc = 1.0 s and Tc = 1.6 s. We have performed 27 dynamic seismic analyzes of these three building cases with the GenEcAm program, for which the relative displacements of the level and the forces in the dampers were obtained as results. The processing of these results allowed us to conclude that for medium-height buildings the maximum relative level displacements decrease by 26%-29% when using viscous fluid dampers with c = 2000 kNs/m2 and by 41%-48% when c = 4000 kNs/m2.
