Abstract: Torsional vibration arises when building has eccentricity of stiffness. For the method that cancels this torsional vibration, damping device is included on flexible side element. Increasing of damping factor on flexible side element, damping factor which maximum response displacement of stiff and flexible side elements becomes equal, exists. This optimum damping factor depends very on eccentric factor for short basic natural period, but does not depend on eccentric factor for long basic natural period. The optimum value of maximum response displacement depends very on basic natural period, but does not depend on eccentric factor for same basic natural period. In this paper, mixed eccentricity of stiffness and damping factor that superimposes with stiffness eccentricity and damping eccentricity after general consideration of those weights, is considered. If those weights are suitably estimated, when this mixed eccentricity of stiffness and damping factor is equal to zero, maximum response displacement stiff and flexible side elements must become equal. From analytical results, it is clear that the ratio of weight of damping eccentricity to the weight of stiffness eccentricity is 2 to 10.
