Proposal for response control structure using viscous wall dampers with deformation amplification mechanism

Response control devices are widely used at the design of high-rise buildings owing to reduce the seismic response considering about the influence of long period ground motion, but these performances are degraded by excessive bending deformations. In order to improve response control performance, this paper describes an analysis method of effective damper deformations and a new structural system which amplifies effective damper deformations. It is confirmed that this system is able to highly reduce responses, particularly in acceleration and shear force, with a small amount of damper owing to high damping effect.
