Abstract
The objective of this study is to examine the effects of viscous supplemental damping on response quantities of asymmetric-plan structures responding in a linearly elastic fashion. The response quantities which will be investigated include: element deformations, base shears, and base torques. These response quantities will be normalized, evaluated, and then analyzed.
It is shown that supplemental damping is indeed effective in reducing element deformations and base torques. In some cases, supplemental damping is also effective in reducing base shears. In order to achieve the largest reduction in flexible element deformation, it is recommended that all fluid viscous dampers be placed on the flexible side. To produce the largest reduction in stiff element deformation, it is best to place all fluid viscous dampers on the stiff side.
Supplemental damping has a greater affect on total base shear than it does on total base torque. In some cases, it is recommended that a design for higher base shear forces be considered. Results from this investigation can be used to help in the design of such factors as foundation forces of structures.
