Abstract
Viscous dampers, as a special type of passive dampers, are efficient tools for seismic improvement of the buildings and eliminating the effects of seismic pounding during earthquakes. Such dampers can be installed between the adjacent buildings or inside them and also at different story levels. This paper attempts to investigate the effects of different damper placements. Accordingly, two single degree of freedom systems connected by viscous dampers were considered first and the dynamic characteristics of the system have been determined. Then, relative displacements of the buildings are compared with damping inside building for one-story models and with free undamped response for two-story models, under ideal white noise seismic input. Absolute accelerations of the one-story buildings are also compared by assigning the Kanai-Tajimi filtered white noise as the input. Results reveal that using dampers between buildings is more suitable than using them inside buildings, as the relative displacement between adjacent buildings would be reduced for lower values of uncoupled frequency ratios of structures and the absolute acceleration would also be significantly reduced for both buildings, rather than just for one of them. Furthermore, use of dampers at the top level would be more beneficial than using them throughout the height of the systems for seismic pounding mitigation.
