Abstract

This paper presents the seism dynamic analysis of a ten-stories building equipped with anti-seismic viscous fluid dampers, in order to determine the influence of the damping coefficient c on the building relative displacements and dampers forces during seism. By modifying the damping coefficient c, three cases of analysis were performed: c = 0 kNs/m2 (for the structure without dampers), c = 10000 kNs/m2 and c = 17000 kNs/m2. 21 design accelerograms were considered for dynamic analysis, seven for each value of the corner period Tc (0.7 s, 1.0 s and 1.6 s). In order to compare the results, the time variations of the relative displacements for each story were determined and the maximum values ​​ were presented on the same graph to highlight the influence of parameter c. The time variations of the damper forces for each story were processed in the same manner. The analysis of the results shows that for c = 17000 kNs/m2 there is a reduction of the maximum relative displacements of up to 50% while the forces in the dampers reach the maximum value of 1000 kN. For c = 10000 kNs/m2 the reduction of the maximum relative displacements is on average 35%, and the maximum damper forces reach values ​​up to 800 kN. In order to establish the optimal value of the coefficient c, an additional study is needed to evaluate the influence of the damper force on the structure nodes area in which the dampers are positioned.
