Tuned viscous mass damper(TVMD)coupled wall system used for high-rise buildings
This paper proposes an innovative coupled wall system,named as the tuned viscous mass damper(TVMD)coupled wall systems.Use of the novel wall system is expected to control both lateral drifts and floor accelerations of high-rise buildings when subjected to strong ground motions,thus enhancing their seismic resilience.The TVMD consists of a stiffness device connected in series with a ball screw device that can provide large inertial and damping forces even under a small deformation.In this system,TVMDs are allocated to connect adjacent wall piers in a zig-zag configuration.Such a strategic arrangement of TVMDs efficiently makes use of the vertical relative displacements of the adjacent walls induced by their flexural deformation to generate the motions and forces of the TVMDs.Multi-mode tuning method is developed for optimal design of this system.Dynamic response analysis is performed on a presentative TVMD coupled wall system.The analysis results indicate that the TVMD coupled wall can effectively suppress both the inter-story drifts and floor accelerations by tuning several modes of vibration.Finally,real-time hybrid simulation is conducted to validate the performance of the proposed system.The test results further demonstrate the benefit of the TVMD coupled wall system,including the robustness to the detuning effect.
