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/m 2 (for the structure without dampers), c = 10000 kNs/m 2 and c = 17000 kNs/m 2 . 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/m 2 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/m 2 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.

“…In order to solve the seismic and vibration reduction problems of existing buildings, many scholars have conducted extensive research. Some scholars have conducted extensive damper design and experiments, and used experimental data to determine the damping coefficient and damping characteristics of viscous dampers [1]; Some scholars have evaluated the impact of different viscous damper damping coefficients on the seismic response of towers by analyzing the impact of towers with different damper damping coefficients on low rise buildings [2]; Some scholars have conducted different types of simulations using modal analysis and seismic time history analysis, and obtained data that can determine the nonlinear characteristics of fluid dampers [3]; Some scholars even use genetic algorithm based search methods to test the optimal distribution of damping coefficients [4]. Scholars have also conducted research on the impact of viscous damping on low-rise reinforced concrete frame structures under earthquakes, compared the seismic evaluation of RC buildings with and without friction dampers, and studied the impact of friction damping isolation systems on the performance of prefabricated concrete buildings [5][6][7].…”

In this paper, the basic principle, secondary software development and practical application of viscous damper vibration reduction technology are studied. The viscous damping coefficient velocity function equivalence method is used, and the secondary development is carried out in the finite element software ANSYS through program compilation, and the operation interface of the velocity function equivalence method is established. On this basis, the complex vibration problems of an existing building are studied, and the arrangement and installation of viscous dampers are guided on site.Through comparative analysis, it is concluded that the UIDL program and APDL macro command stream in the finite element software ANSYS can be used to establish the operation interface of the speed function equivalent method, which makes the method have better applicability and operability, improve the work efficiency and facilitate the popularization and application. By adopting the nonlinear viscous damper damping technology, before the structure and equipment produce strong vibration, the damper first enters the energy dissipation state, produces large damping, greatly consumes vibration energy, and rapidly attenuates the dynamic response of the structure and equipment to ensure the safety and normal use of the structure and equipment.The field dynamic test results and the finite element analysis results both show that the viscous damper vibration reduction technology based on the velocity function equivalent method has a significant vibration reduction effect, and is an effective means to solve the existing building vibration problems.

Abstract. This paper presents analytical, numerical and experimental studies of SERB TEL-150 new Romanian devices for dissipation of seismic energy for buildings affected by Romanian Vrancea earthquakes. These devices were invented to be positioned at the foundation of buildings and were tested in static cases. The purpose of these studies is to determine the analytical model of the special shape hysteresis of these new devices which is necessary to obtain the mathematical equation for these hysteresis curves. The experimental and the numerical analysis of SERB TEL-150 were performed in order to determine the experimental and the numerical hysteresis curves which are to be modeled with a modified Bouc-Wen model. These devices were invented by PhD.eng. Viorel Serban (CITON -Center for Technology and Engineering for Nuclear Projects) and they were used for equipping NAVROM building in Galati, Romania.
