Viscous Damper Optimization in Low-Rise Adjacent Buildings Exposed to Earthquakes by Considering the Soil-Structure Interaction
In this study, the difference between the displacements of structures (relative displacement) is selected as the control parameter in pounding problems. During an earthquake, an increase in the amplitude of relative displacement between adjacent structures indicates a potential pounding condition. W...

| description | In this study, the difference between the displacements of structures (relative displacement) is selected as the control parameter in pounding problems. During an earthquake, an increase in the amplitude of relative displacement between adjacent structures indicates a potential pounding condition. Within the scope of this study, the optimal distribution of linear viscous dampers between adjacent structures and the effect of soil on this distribution are investigated. The structure is intended to be modeled in two different ways through rigid and three sandy soil models (loose, medium-dense, and dense) at the foundation level. Different analyses are performed by changing the total damping coefficient considering the 1st and 2nd modes of the coupled models of adjacent structures. The study presents important findings on how to design dampers to prevent pounding problems in adjacent buildings, especially in seismically hazardous regions. Within this study, an adjacent building model 5-5 story is examined. The optimum damping coefficients are compared, and their effectiveness is demonstrated using the first periods of both adjacent building models. The proposed method in the study shows that it is possible to minimize the collisions of adjacent structures with the optimum placement of viscous dampers. The method shown is quite effective for the design of dampers that will be added to the structures later or at the initial stage. |
