| Abstract: |
In this paper, the efficiency of using viscous dampers to connect two walls, in discrete locations along the height, is examined. The non-dimensional parameters controlling the behaviour of such structures are first identified. Those are a non-dimensional damping coefficient and the non- dimensional heights where the dampers are mounted. Then, a parametric study is conducted to gain some insight on the behaviour of the system and to attain graphs for important non-dimensional responses of interest such as displacements, inter-story drifts, absolute accelerations, wall base- shear, total base-shear and total over-turning moments. These reveal the optimal locations of the dampers and allow a simplified analysis and design. |
